The Justice League of America is DC Comic's premier super-hero group, comprised of many of its most powerful and recognizable characters. The current incarnation of the League was introduced after the events of Cry for Justice.

First appearing in The Brave and the Bold #28 (February/March 1960), the League originally appeared with a line-up that included Superman, Batman, Wonder Woman, Flash (Barry Allen), Green Lantern (Hal Jordan), Aquaman, and the Martian Manhunter. However, the team roster has been rotated throughout the years with characters such as Green Arrow, Atom, Hawkman, Hawkgirl, Black Canary, Captain Marvel, Plastic Man, Red Tornado, other Green Lanterns, and dozens of others. The team received its own comic book title in October 1960, when the first issue was published, and would continue to #261 in April 1987, which was the final issue. Throughout the years, various incarnations or subsections of the team have operated as Justice League America, Justice League Europe, Justice League International, Justice League Task Force, Justice League Elite, and Extreme Justice.
Thnaks comicvine for help.
Henry Cavill as Superman/Clark Kent
Although Superman's origin story has been retold and revamped many times, there has always been a basic origin story which most people are familiar with. Superman's basic origin story tells of his birth as Kal-El to renowned scientist Jor-El and his wife Lara on the alien planet Krypton. When Jor-El discovers that the planet is going to explode, he sends his child Kal-El to Earth in a spaceship, which crashes in a field in the state of Kansas. Johnathan and Martha Kent find the wreckage and raise Kal as their own, naming him Clark and teaching him simple, honest morality. As his powers emerge, he moves to the city of Metropolis to battle injustice in all its forms.
You know one moment I thought that Joe Manganiello is better for Superman,but then I changed my mind.And now I think that Cavill is the guy which can play superman better than Rout or even Manganiello.
Scott Adkins as Batman/Bruce Wayne
A wealthy philanthropist Thomas Wayne, his wife Martha and their 8 year-old son, Bruce were coming out of a movie theater. As they stepped onto Park Row (now called Crime Alley) a masked gunman named Joe Chill came out of the shadows. Chill shot and killed both Thomas and Martha in cold blood right in front of their young boy. Bruce was traumatized at the sight of his parents' death and his life would never be the same. After his parents' death, Bruce was raised by his wise and loyal butler Alfred Pennyworth and inherited his family's vast fortune as well as his father's company, Wayne Enterprises. Facing his parents' gravestones, Bruce made a solemn oath to avenge his dead parents. He toured the world looking for experts on various fields, training himself mentally and physically.
So Bale is the stable actor of Batman until film of Dark knight rises(2012).After it I hope that the next producer will change actor.Bale is a good actor, but I think that Edkins is the guy which we need for Bruce Wayne.His acting in film Ninja was great.
Bridget Regan as Wonder Woman/Dianna Price
Wonder Woman was born into the Amazon race. A soul of a previously deceased woman was reincarnated in a child-sized formed of clay. Hippolyta gave the name Diana to the new princess of the Amazons. She was given beauty and a kind heart from Aphrodite, wisdom from Athena , strength and endurance from Demeter , hunting instincts and animal-communication from Artemis , as well as speed and flight from Hermes . Diana enjoyed the privilege of being raised as child on an island of adults and many Amazons took a maternal approach to her. Diana was also different as she displayed more mercy and a desire for peace that was uncommon among the Amazons. When it was decreed by the gods that an Amazon go forth into man’s world, Diana entered a contest to decide who this would be, despite her mother’s wishes. Upon being victorious she was chosen as the envoy to man’s world from the island, and she assumed the iconic armor and lasso.
This actress has similar look and she can aprove this role.
Ryan Mcpartlin as Flash/Barry Allan
As a kid, Barry had a love of superheroes with his favorite being Jay Garrick, The Flash. While working late one night at the Police lab, a bolt of lightning came through the open window; striking a chemical rack nearby. The chemicals exploded, splashing Barry.When he stood he found himself unharmed but incorrectly found that time had slowed down when in reality he was moving at super speed. Inspired by Jay Garrick, he decided to use his new found powers for good; becoming The Flash in honor of Jay Garrick.
What about of this guy I think he has look of Barry Allen and in suit he will look awesome.
Chris Pine as Green Lantern/Hal Jordan
Hal Jordan was chosen to be Green Lantern 2814 by the dying alien, Abin Sur. Hal has since been widely considered the greatest Green Lantern. Recently however, Hal Jordan has been removed from the Corps and is no longer a Green Lantern.
I didn't like acting of Ryan Reynolds,because Hal is serious character and Ithink that Chris Pine is the guy which must have this role.Some guys say that he is good for Flash,but this isn't right because this guy is awesome for this role.
Liam Hemswoth as Aquaman/Arthur Curry
Aquaman is the king of the seven seas and ruler of Atlantis. He is one of the founders of the Justice League of America and one of DC Comic's most recognized heroes.
This was a special choice,because the brother of this guy is Thor there is no need to give him role of Aquaman instead of it this role will suit his brother Liam Hemsworth.
Christopher Meloni as Martian Manhunter/J'onn J'onzz
J'onn J'onzz was teleported to Earth from Mars and stranded here 50 years ago. He used his extraordinary abilities as the Martian Manhunter, and was a faithful member of every incarnation of the Justice League. He has been resurrected recently and will be apart of Stormwatch in September.
Meloni is going to play role of Colonel Hardy in film Man of steel,but I want him to be martian manhunter,because he suits for role of Jonn Jonzz,and what about of MM CGI will manage this problem.
Karl Urban as Hawkman/Carter Hall
Carter Hall, while on an archeological expedition in Egypt, uncovered ancient weapons and armor made of the Thanagarian gravity-defying Nth metal. After learning that he is the reincarnation of an Egyptian prince, he dons the armor and becomes the savage Hawkman.
If you have seen him in series of Hercules:Legendary Journys you will understand me.
Kelly Overton as Hawkgirl/Shiera Hall
Hawkgirl is the reincarnated spirit of Chay-Ara. Reborn every generation as a curse, the most current Hawkgirl goes by the name of Shiera Sanders.
She is very talented actress and she will manage role of Hawkgirl and will look nice near Karl Urban.
Serinda Swan as Hawkgirl/Kendra Saunders
Shiera Hall was unwilling to leave Carter who remained alive after the events in Zero Hour. So her soul found her way to her Grandniece, Kendra Saunders, who had just committed suicide. Shiera's soul entered Kendra's body as Kendra left it. However, she retained no memory of her previous lives with Carter.
I have decided to give this roel her because in my opinion her she has all details to be hawkgirl.
Daniel Cudmore as Captain Mavel/Billy Batson
Chosen by the wizard SHAZAM, whenever he utters the word "SHAZAM!", young Billy Batson is empowered with the powers of the elders and transformed into the World's Mightiest Mortal, Captain Marvel.
He has the best look to be chosen for this role.
Ryan Gosling as Green Arrow/Oliver Queen
Green Arrow is the protector of Star City, ex-husband of Black Canary, teacher of Arsenal, father of Connor Hawke, mentor to Speedy, member of the Justice League, fighter for the "little guys" and the finest archer of the DC Universe.
I don't see anyone else except Ryan Gosling.
Mark Wahlberg as Wildcat/Theodore Grant
Pro-boxing star Ted Grant, inspired by stories of The Green Lantern, became a superhero to clear his name. Wildcat has served as a mentor to many younger heroes including Batman and Black Canary.
Megan Fox as Zatanna/Zatarra
The daughter of John Zatara, Zatanna is a powerful magician who casts spells by speaking backwards and works as both a stage performer and a member of the Justice League.
This character is special for her,without any doubt.
Patrick Wilson as Atom/Ray Palmer
Ray Palmer was the second to take up the name, Atom, and was one of many Silver Age reboots of golden age characters based more on science. Two others have taken the name after him but he has been the prominent of them in the DC Universe.
Though that fan favorites prefer this guy as Flas,but role of Atom will suit much more than it.And if you see this character unmasked,you will be amazed,because he totallylookslike Patrick Wilson.
Matthew Mcconaughy as Captain Atom/Allen Adam
A hero with deep ties to the Government, Nathaniel Adam was coerced into an experiment which bonded an alien metal to his skin and sent him 18 years into the future, giving birth to Captain Atom, a superhero fueled by the Quantum Field.
This role is special this actor.
Scarlett Johanson as Black Canary/Dinah Drake Lance

In the 1960s, the Justice Society of America and Black Canary were revived and put on an alternate universe dubbed Earth-Two. When Dinah returned, it was explained that since the time she had been gone, she went on to marry Larry Lance. Dinah along with the JSA teamed up with the Justice League Of America on several adventures, regaining her status as JSA member. When a mission pitted the team against an alien creature named Aquarius, Larry Lance was killed in an attempt to save Dinah’s life. After they defeated the alien, Dinah was in mourning and decided to leave Earth-Two and move to Earth-One to start a new life. She started by joining the Justice League of America, and she soon began dating JLA teammate Green Arrow. Also during this time she discovered that she mysteriously gained the ability to do an ultrasonic scream, she would call it the “Canary Cry.” Canary would then join the Justice League of America, becoming the only Golden Age and Silver Age hero to have been on the JLA and JSA roster.
The actress of this character must be sexy and blonde,so I don't see anyone else except Scarlett Johasnon,she has all things which we need for this character.
Dianna Agron as Black Canary 2/Dinah Laurel Lance
After Crisis on Infinite Earths, Black Canary's origin was changed to become two different characters. Now there was a Black Canary named Dinah Drake Lance, and her daughter, the current Black Canary, named Dinah Laurel Lance. Dinah Drake would marry a private investigator named Larry Lance, acquaintance of James Gordon. A few years later they had a baby girl, named Dinah Laurel Lance. Dinah would grow up surrounded by her mother’s friends from the now disbanded JSA, who acted as her babysitters and surrogate aunts and uncles. Seeing all the good that the JSA was able to do, Dinah desired to become a hero and help the world as well.
Dianna Agron will suit as Black Canary for modern age.
Katheryn Winnick as Power Girl/Kara Zor-L
Power Girl is a Kryptonian, a member of the Justice Society of America, and one of the few survivors from Earth-Two after the Crisis on Infinite Earths. She is actually Kara Zor-L, the Supergirl from Earth-Two.
I'm sure she will perform very cool,everything what she needs is a little CGI effects with her body.
Billy Crudup as Dr.Fate/Kent V. Nelson
Kent V. Nelson came into possession of the Helm of Nabu, succeeding Hector Hall as the new Dr. Fate.
This actor has played role of Dr.Manhattan great,and I'm sure that he will perform this role too.
Russel Brand as Plastic Man/Patrick Edward O'Brian
Former Criminal Patrick "Eel" O'Brian became the super elastic superhero known as Plastic Man. Often the joker of the group; he can stretch in to any imaginable form.
For first look it seems not very suitable,but I think that Brand will be awesome for this role,he just need to shave his beard and cut hair for look.
Alex O'laughlin as Question/Vic Sage
The man to be known as Vic Sage was previously Charles Victor Szasz, an orphan who had grown up in Hub City. Charlie spent most of his childhood at an orphanage, where he was considered a troublemaker. Charlie was often beat by the nuns who ran the orphanage and harassed by the other children. Eventually he was able to get to college where he studied journalism and became a reporter who worked for stations like KBEL. However, this career did not help him to control his violent tendencies. He eventually met Aristotle Rodor, who helped him put his anger to use by creating the identity of the Question. Before changing his named to Vic Sage, and returned to Hub City after many years.
This actor is very talented and I just think that he can bring this character good look and fame.
Ashton Kutcher as Vibe/Paco Ramone
Paco, a young Puerto Rican breakdancer with the mutant ability to cause strong vibrational waves, a smart mouthed attitude and a thick (affected) accent, Vibe joined the Justice League new line-up. Vibe was asked to join when Aquaman decided to re-vamp the team, allowing truly "dedicated" round the clock members.
This actor is very cool and funny he will look amazing in this role without any doubt.
Hayden Christensen as Elongated man/Randolph William Dibny
A long time member of the Justice League who recently lost his wife. Trying to make sense of his life post-loss, he sacrificed himself in battle. For a brief period of time he was a Black Lantern, but was destroyed by Indigo-1.
Well I think that actor of this character must be a bit tall and thin,I couldn't fin out anyone except Chritensen.
Josh Duhamel as Booster Gold/Michael Jon Carter
Humiliated in his own time-period, the 25th century, Michael Jon Carter steals future technology and a security robot named Skeets and travels back into the 20th century to become the heroic Booster Gold. He is now the Guardian of the Timestream and protects it with the help of Rip Hunter.
Duhamel is a great actor and I think that he can give this character a good appearance in movie.
Edward Norton as Red Tornado
An android created by the supervillian T.O. Morrow to infiltrate the Justice Society of America. Now it is a noble superhero and member of the Justice League.
This guy is a great actor and I think that this role will suit him.
Ewan Mcgregor as Starman/Kallor
Thom was born on a orbital satellite over the planet Xanthu in the 30th century. His parents were astronomers and Thom was born with the meta ability to control gravity. After crashing his parents' space cruiser through the tail of a comet, Thom also gained abilities that rivaled that of ancient Kryptonians. Feeling heroic, he adopted the name Star Boy and joined the Legion of Super-Heroes.
The actor for this character must be actor from Star War films and I think that Mcgregor is the one.
Matthew Fox as Blue Beetle/Ted Kord
Ted Kord was the second person to become the Blue Beetle. Deprived of the scarab that empowered his predeccesor, Ted was forced to rely on his superior athleticism, fighting prowess, and technological genius to combat crime. He died a hero fighting Maxwell Lord.
Jon Hamm as Phantom Stranger
One of the most enigmatic beings in the universe, the Phantom Stranger only appears when events of great magnitudes necessitate his direct involvement. Mysterious and all knowing, at one with the cosmos, but forever alone.
I think that Hamm suit for this role much more than for Batman or Martian Manhunter.
Holly Valance as Fire/Beatriz Bonilla da Costa
Beatriz Bonilla da Costa had originally been bequeathed with her powers due to Brazilian mysticism. She was the President of Wayne Enterprises' Brazilian Branch. She has served as a member of various teams, but Fire is most well known for her team-ups with her best friend Ice.
Elisha Cuthbert as Ice/Tora Olafsdotter
Tora is a member of a race of magical ice people that live in the mountains of Norway. Her father, King Olafsdotter is the leader of these people.

After Rod introduced Tora to Doctor Mist and the Global Guardians she joined the team as the second Icemaiden. Soon after, she became close friends with Beatriz DaCosta. After the Global Guardians lost their U.N. funding, Tora and Beatriz applied for membership in a depleted Justice League International that was desperate for new members. Changing her name to Ice, Tora fought with the League for years.
Josh Hutcherson as Superboy/Kon-El
The original Superboy was the Silver Age Superman as a young teenager who grew up in Smallville. When he went to Metropolis and graduated from Metropolis University, he became Superman. In 1986, Superman's history was retconned in the Man of Steel mini-series and Superman never had a career as Superboy. In Legion of Super-Heroes vol 2 #38 (1987), the Time Trapper revealed he created Superboy and Superboy died saving the Legion from the Time Trapper.
The Superboy from Earth-Prime, Superboy-Prime, first appeared in DC Comics Presents #87 (1985) and eventually became known as Superman-Prime.

The original Huntress was Paula Brooks and was a super villain in the Golden Age. The second Huntress was Helena Wayne, the daughter of Batman and Catwoman from Earth-Two. After the Crisis, Helena’s origins was revised during her own limited series. Helena believed her father to be Franco Bertinelli. Helena witnessed her parents’ (Franco Bertinelli and Maria Panessa) murder at the age of 8. The hit was ordered by Steven Mandragora, capo of a local Mafia family.

Rosie Huntington Whiteley as supergirl/Kara Zor-El
s533x800-111308-580-tile-tile-tile-tile.jpg" />
Among the many incarnations of Supergirl, the most prominent and current "Girl of Steel" is Kara Zor-El, Superman's cousin and last survivor of Krypton's Argo City. Supergirl stands for truth, justice and the American way!
Her acting was great in Transformers 4.I think that role of supergirl will suit her like none.
Armie Hammer as Citizen Steel/Nathan Heywood
Nathan Heywood is the grandson of the original Commander Steel aka Henry Heywood and the cousin of the previous Steel, Henry Heywood III. Despite having a promising American Football career, he was forced to retire early due to an injury to his knee which completely shattered the bone.

This attack results in the majority of the Heywood family being brutally killed including Nathan's brother and mother who were turned into statues by the metallic Reichsmark.Just as Nathan was about to receive similar treatment he stabbed his crutch into the villains mouth which caused him to spit metallic blood all over Nathan. Eventually Hawkman appears to save the remaining members of the Heywood family, Nathan and a few children and takes Nathan to Dr. Mid-Nite who informs him that his body for some reason is absorbing the metallic blood and Nathan goes into a coma.
During this coma a metallic leg grows were his amputated one was previously. Eventually he awakes and realizes that with his new leg he has gained superhuman strength and that his body is living steel due to it absorbing the properties of Reichmark's blood.

During his first adventure Buddy was met by a large alien beast, presumably from the crash, but later discovered to be the envoy of the other aliens (important to Buddy later in his life) with similar powers to his. After a fight in the town, Buddy lured the beast back to the mountain range by attacking it with a fire truck. Once there, the hulking alien destroyed the truck, but was defeated when Buddy exposed the alien to frightened field mice. The alien took on the attributes of the mouse, as well as its fear. Initially Buddy only displayed the powers of the Animals he came in contact with during the manifestation of his powers: the Tiger, the Gorilla, the Elephant and the Sea Lions, but he later progressed onto other Animals.

After the destruction of the rock by the Spectre, the Scarab landed in a vacant lot in El Paso, Texas. There it was found by a high school student, Jaime Reyes. The scarab bonded itself to Jaime's body, and entered into a far more interactive relationship with the boy than it had with Dan Garrett. The scarab now allows Jaime to cover himself in a kind of bio-mechanical armor, which can be modified to enhance his speed and strength, as well as to create weapons, wings and shields. Batman and his group tracked down Jaime because the Scarab was the only thing that could find Brother Eye and stop it.
