This is my cast for some of the people that i think should be in a sequel. I might write a seriese of stories and i wanted to do this before i wrote anything. This is my first big casting so try to go easy on me. Hope you enjoy!
Demián Bichir as Bane
An escaped prisoner from an island prison in South America, Bane has abnormal strength as a result of having had experiments with a derivative of the drug Venom performed on him. He now uses the Venom as and strength enhancer for battling his foes, like Batman. He is one of Batman’s most intelligent and powerful foes.
He is an incredible actor as Fidel Castro in El Che and plays an intimidating mobster in “Weeds” he is definitely threatening enough and smart enough to play Bane. Although he might be old CGI could make him look younger and bigger on screen.
Cameron Bright as Anarchy/Lonnie Machin
A teenage prodigy who, believing in anarchism creates improvised gadgets and attempts to challenge the established order to improve society. Initially very young (age 12), his costume was designed to disguise his true age. More recent stories portray him as being in his late-teens. Batman recognizes him as a force for good, but does not support his violent methods
He has played rather creepy characters in movies such as Godsend and Butterfly Effect and would be able to hold his own against Christian Bale. He also played Leech in X-Men: The Last Stand. He could be portrayed just as the Joker was, as a person fighting against society.
Adrien Brody as Roman Sionis/Black Mask
Born into an upper class family that rivaled the Wayne’s, he later killed his parents, lost their fortune, and turned to crime. He wears a black mask and requires his gang to wear masks in his presence too. Interestingly, he targets Bruce Wayne rather than Batman. After kidnapping a number of Wayne Enterprises’ executives, he gets caught in a fire and his mask is melted onto his face, disfiguring him. Also he has been a strong organized crime leader in Gotham. Roman Sionis was originally in the script of The Dark Knight but was taken out during production.
Brody is a outstanding actor that brings an extraordinary performance to every movie. He looks like he could be a business man one minute, and a deranged mob boss the next.
Doug Hutchison as Calendar Man/Julian Day
Calendar Man is a criminal that commits brutal murders on holidays. His crimes always have a relationship to the date that they are committed. The theme may be related to what day of the week it is or to a holiday or to a special anniversary on that date; he will plan his crime around that day. He often wears different costumes which correspond to the significance of the date, though he does have a main costume which has various numbers sprouting from the shoulders.
Doug always plays crazy and frightening characters. In Green Mile he played a crazy guard that beat inmates and in Punisher Warzone he was a cannibalistic psycho. He could easily pull off the role of a holiday serial killer.
Kate Beckinsale as Selina Kyle/Catwoman
She started as a criminal who wore a cat-themed costume and often operated as a burglar, has a love/hate relationship with Batman. For years, she skirted on the edge between villain and antiheroine. However, she has largely reformed in recent years, adopting the role of the guardian of Gotham City's crime-infested East End, though she still comes into conflict with Batman on occasion. She has also been known to take revenge upon those who commit crimes against animals, especially cats. She also holds a dark past of being a prostitute that struggled to free herself from a dark life.
Kate Beckensale is sexy, a great actress, and a bad ass fighter. She has shown her fighting ability in Underworld and Van Helsing and could be a formidable opponent against Batman.
Ryan Phillippe as Catman/Thomas Blake
A world-famous trapper of jungle cats who turned to crime because he had grown bored with hunting and had squandered most of his fortune. He became a burglar who committed his crimes in a cat suit made out of an ancient African cloth he believed gave him a cat's nine lives.
He has played intense roles in Flags of our Fathers and Crash and could also portray the jack-assness of Catman
Mickey Rourke as Basil Carlo/Clay Face 1
Basil Carlo was an actor that went crazy when he found that a movie that he previously starred in was getting remade. He donned the persona of Clayface, the killer from the movie, and wreaked havoc on the crew of the movie.
Mickey would be perfect for the role due to his recent acting comeback and his general style of acting.
Christian Slater as Arthur Brown/Cluemaster
Cluemaster is a violent criminal that slaughters his victims and leaves clues behind. Arthur Brown was a failed game show host who turned to a life of crime, leaving trademark clues as to his actions. He is frequently imprisoned in Blackgate Penitentiary, and also has an estranged daughter, Stephanie Brown, alias the masked vigilante Spoiler. Although Spoiler was originally inspired to take up her costumed identity as a means of combating her dad, she would eventually turn into a full-fledged crime fighter, even at one point replacing Tim Drake as Robin.
Christian Slater has played a lot of bad ass characters and would be able to pull this off as well. He looks like a man that would easily lose his cool when things went bad and start a life of crime. He played an evil murderous character in Hollow Man 2 and would be believable as a psychopathic murderer.
Jeffery Dean Morgan as Floyd Lawton/Deadshot
Deadshot is often a hired assassin. He uses a large variety of weapons and extremely skilled with them. He first appeared in Gotham City as a new crime fighter, but is revealed to be an enemy of Batman when he attempts to replace him. He is sent to jail when Batman and Commissioner Gordon publicly expose his plot to become the king of Gotham's underworld.
There is no need for explanation. Jeffery Morgan is extremely talented and would be great in this role. He previously portrayed a similar character as The Comedian in Watchmen
Wentworth Miller as Garfield Lynns/Firefly
Garfield Lynns, a down-and-out film Visual effects expert attempts to rob a theater by faking a fire, only to be stopped by Batman and Robin. He escapes, and in the darkness Batman sees a distant firefly, which he mistakes for Lynns' lit cigarette and chases in the wrong direction. Inspired, Lynns becomes The Firefly, using various lighting effects and optical illusions in his crimes.
Wentworth Miller is an outstanding actor with a creepy look to him. In Prison Break he displayed a creepy genius and an eerie monotone voice. Firefly should be around the same age as Batman.
Brittany Murphy as Harley Quinn
A former criminal psychiatrist fell in love with the Joker and became his most famous accomplice. She wears the outfit of a traditional harlequin jester.
Brittany Murphy is a fan favorite for the role. She can portray a dark character as seen in Don’t Say a Word and a comedic character in Just Married.
She has done a number of serious roles that would make her great for this character.
Jean Reno as Hugo Strange
Hugo Strange is an insane psychologist who knows Bruce Wayne's secret identity and lusts to take the identity for himself. In Arkham Asylum he is believed to have preformed horrible experiments on the inmates.
He has the look and acting ability for Hugo. In movies like Ronin and The Da Vinci Code he showed great acting ability and would be able to bring the same to Batman
Matt Dillon as Thomas Eliot/Hush
Thomas Elliot was a childhood friend of Bruce Wayne's. He targets both Batman and Bruce Wayne. Although Hush's name originates from a nursery rhyme, Hush lives up to it by using manipulation and guile instead of noisy "signatures". Hush wished for his parents to die so he could obtain their fortune. Thomas Wayne thwarted this plan when he was able to save Thomas’s mother. This led to much anger towards the Wayne’s.
Matt Dillon would be great for this role. He is also my favorite pick for someone to take over if Christian bale quits batman. He has a general look of evil and could look like a friend of Bruce Wayne’s.
Tony Todd as Waylon Jones/ Killer Croc
Killer Croc is a large, muscular African American man with a scaly skin condition. Of all his previous designs, this is the most human. He has also been portrayed as a man that was mutated into a reptilian monster. He is missing his abnormally long snout, tail, and claws. Croc has been seen a leader of a gang of black thugs, and later being a high level member of Joker's newly formed gang.
He is really a great man for the role. Most people want the guy from Underworld but I feel that Todd is better. He has more acting experience and an intimidating look and voice.
Tobby Kebbell as Drury Walker/ Killer Moth
The original Killer Moth is a prisoner identified only by his prison number, 234026. While in prison, he reads a newspaper article about Batman and decides to set himself up as the "anti-Batman," hiring himself out to Gotham City's criminals to help them elude capture by police. Upon his release, he uses the hidden proceeds of his crimes to build a "Mothcave", modeled on the photos of the Batcave in the newspaper article he read. The 1990s, in the Post-Crisis continuity, Killer Moth's real identity is revealed as Drury Walker, an unsuccessful criminal whom no one takes seriously.
A young British Actor that could be a criminal that no one takes serious. In RocknRolla, he was a dark character and also comic relief, just as Killer Moth should be.
Doug Jones as Kirk Langstrom/Man-Bat
Dr. Kirk Langstrom, a scientist specializing in the study of bats, develops an extract intended to give humans a bat's sonar sense and tests the formula on himself because he is becoming deaf. While it works, it has a horrible side effect: it transforms him into a hideous man-sized bat.
Doug Jones is truly the actor that can turn into anything and still holds acting ability. He looks like he could be a scientist and could be turned into a bat with some CGI and make-up
Ralph Fiennes as Victor Fries/ Mr. Freeze
Dr. Victor Fries was formerly a scientist and is an expert on cryonics. He tried to cryopreserve his stricken wife Nora Fries until a cure was found to her disease. During the process, an accident caused his body to function only below freezing point, requiring him to wear a special self-contained refrigeration suit. He uses similar ice technology for weapons.
Ralph Fiennes shows his acting ability in all movies and never disappoints. Although he might be too you for the usual Victor, it would be much more believable for a younger person to survive the incident and become a criminal.
Bill Murray as Oswald Cobblepot/the Penguin
Oswald Cobblepot, a short round man with a long pointed nose, fancies himself a gentleman of crime. He usually wears a tuxedo, top hat, and monocle, and carries any variety of umbrellas which have various hidden functions such as vehicles or weapons. He is one of Batman’s most popular villains.
I know many will be against this choice. But he looks a bit like The Penguin and could pull off a gangster/business man. He has a lot of acting experience and even though he has done many comical roles, he could be serious if the part was given to him.
Elizabeth Hurley as Pamela Isley/ Poison Ivy
Pamela Isley was a student of advanced botanical biochemistry. She has the ability to control/manipulate all plant life and is immune to all poisons and toxins. She is often described as fanatical about defending plants from other humans, even being willing to murder for her beliefs.
Poison Ivy needs to be a beautiful sexy woman that can act. Hurley was my first choice but i thought she was too old. I forgot Kidman was in Batman Forever.
Michael C. Hall as Edward Nigma/The Riddler
Edward Nigma is a criminal mastermind who has a strange compulsion to challenge Batman by leaving clues to his crimes in the form of riddles and puzzles. Recently, he has seemingly abandoned his criminal lifestyle and has opted to utilize his skills to turn a profit as a freelance investigator.
Hall is a great actor that would do well as the Riddler. He plays a cynical part in Dexter that he could bring to The Dark Knight Sequel. He has even expressed interest in the part and is for some a fan favorite.
John Lithgow as Arnold Wesker/The Ventriloquist
George Dzundza as Scarface
Arnold Wesker is a small, mild-mannered ventriloquist. His puppet is a gangster named Scarface. Under the puppet's psychological influence, Wesker becomes a dangerous criminal and crime boss. It has been implied that the Ventriloquist suffers from multiple personality disorder but he in fact is more likely to suffer from dissociative identity disorder.
John Lithgow has that look of psychotic murderer that could portray the Ventriloquist and give you an eerie vibe. George Dzundra voiced Scarface and Arnold Wesker in the 90’s Batman show and could bring the voice back for the movie.
Sam Niel as Jarvis Tetch/The Mad Hatter
Jervis Tetch, criminal name indicates he takes the appearance of the Mad Hatter from Alice's Adventures in Wonderland. He is an insane neuroscientist and developed hardware that can control the brain and induce hypnotic states, and often uses hats or other headgear for mind control.
Sam Niel has the crazy look of Mad Hatter and has acted enough to bring class to the role.
Dominic West as Tony Zucco
Tony Zucco is a mob boss, who is responsible for the death of Dick Grayson's parents. Despite some variation, the basic recurring themes are that Zucco tries to extort the circus the Graysons work for. When the ringmaster refuses to pay him, he sabotages the act causing the highwire ropes to break and sending Dick's parents falling to their deaths.
Dominic West played a cool mobster in Punisher:Warzone. He isn’t well known but has done many great roles such as Theron in 300 and Jasper in 28 Days. He is skilled and would be good at this role.
Brian Cox as Rupert Thorne
Prominent head of one of Gotham City's top smuggling gangs. He is also the boss of "Matches" Malone, the criminal whose identity was taken over by Batman.
He’s a great actor at a great age for this role. He looks like Rupert Thorne and with his experience he could act like him as well.
Alan Dale as Lew Moxon
A mob boss who hired Joe Chill to kill Thomas Wayne which sparked Bruce Wayne into becoming Batman, as well as bringing the villain Zeiss to Gotham City.
He’s a great actor with a great look of evil. He could be believable as the guy that orders Bruce’s parents killed.
Tony Sirico as Sterling Silversmith
Sterling Silversmith has been obsessed with silver since childhood and, now, as a silver-haired older man, has amassed a fortune in stolen goods. Bullets bounce off Silversmith thanks to a silver alloy woven into the fabric of his white suit. Batman has fought him twice, and once prevented Silversmith from murdering the Crime Doctor.
He played a great mobster in the Sapranos and could be as good in The Dark Knight Sequel.
Togo Igawa as Clement Carp
Clement Carp is a Chinese crime boss in Gotham City. He takes control of the underworld and almost succeeds in defeating the Batman, before apparently being killed by Killer Croc, a former member of the Squid's gang.
Togo is a great actor and has been in many great movies such as Memories of a Geisha and The Last Samurie.
