Superman-Brandon Routh
Imo he is Superman. He has the look for Superman and you may say Superman Returns was rubbish but he was great and had to work with a crappy script! But if I had to cast someone else then definitely Henry Cavill! He'd be much better than Owain Yeoman, Joe Manganiello or Jon Hamm! My third choice would be Armie Hammer!
Batman-Josh Hartnett
With Christian Bale's reluctance to do a JLA movie, I thought I should cast someone else as Batman. I had many choices but I believe Hartnett may be the perfect pick! He has the chops, looks and height to portray the brooding bat! He was linked with Supes but I think he'd be a much better Batman! I also thought Chris Pine would make a great, younger Batman!
Wonder Woman-Scarlett Johansson
Yes she played Black Widow in IM2 but imo she would make a perfect WW! She's stunningly beautiful, has the look of WW and she obviously has the chops. Plus she's got a great bust :P, Kate Beckinsale would be my choice if I had to choice someone else!
Green Latern-Ryan Reynolds
He's already been cast as Green Latern and I honestly couldn't think of a better choice for GL. From the looks of the trailer I think he will be a great Hal and GL will be one of the biggest movies of 2011!
Flash-Matthew Fox
I had my doubts over casting Fox for Flash as I wondered whether I could vision him as the Scarlet Speedster and almost cast Ryan Kwanten as a younger Barry but Fox has the chops and look and I would have confidence in Fox nailing the role.
Martian Manhunter-Jon Hamm
Hamm has been linked with many CBM but credit goes to LEEE and a few others who have backed Hamm for the role of Manhunter. I think Laurence Fishbourne should voice the Martian side of John Jones but leave Hamm to do the acting
Aquaman-Josh Holloway
Like Hamm, Holloway has also been linked with quite a few CBM roles but I think Aquaman would suit him the best with him being portraying a young Aquaman. I did consider Kevin McKidd but Holloway would own as Aquaman!
Green Arrow-Ewan McGregor
A fan favourite for the role, he has the looks for Arrow but I think would just need to bulk up a bit more. He would be much better than others such as Jon Hamm, Josh Holloway and Brad Pitt as I feel he would really bring the character alive!
Hawkman-Joe Manganiello
I had always championed Gerard Butler for this role but after cast Joe in this role I have now ever since envisioned Manganiello for this and he would be perfect. He has the build, look and acting chops for Hawkman.
Hawkgirl-Jessica Biel
A fan favourite for the role and always been my choice for Hawkgirl. She is beautiful and has CBM experience from Blade Trinity.
Captain Marvel-Patrick Warburton
Warburton looks like the spitting image of Captain Marvel. His face and build is perfect imo for Captain Marvel and would be fantastic as Shazam. Some may say he's too old but you could just introduce him as a seasoned Captain Marvel.
Captain Atom-David Boreanaz
I had trouble choosing this pick as I couldn't think of someone who would suit this role but I ended up picking a one-time Batman contender, David Boreanaz. Once I thought of David it stuck as he looks like Atom and has the muscle to portray him!
Doctor Fate-Daniel Craig
Credit to @GotBatman for this one choosing Dr Fate was another role I had trouble picking so I eventually had to steal a pick, tut tut :P! But I agree that Daniel Craig would be a great choice for Fate.
Booster Gold-Ryan Gosling
I only ever had one choice for this and it was Gosling. He is so perfectly suited for the role and so it would be impossible to cast someone else as Booster as Gosling was so perfect!
Sandman-Anthony Michael Hall
I believe that Anthony Michael Hall would be fantastic as the mysterious Wesley Dodds. I think Hall would suit Sandman's presence and would be a great Sandman.
Plastic Man-Jim Carrey
Jim Carrey would be great as Plastic Man and he would bring a more humorous side to the character which would be great for audiences. Most importantly he looks like the character and would make Plastic Man more well known and famous to the general audience if a big name like him portrayed him.
Nightwing-Milo Ventimegilia
Milo would absolutely own as Nightwing and I much prefer him over Ian Somerhalder who I cant stand and I would hate it if he ruined one of my favourite characters. Milo has had hero experience in Heroes and would be fricking amazing as the solo crime fighter Nightwing.
Robin (Jason Todd)-Shia LeBeouf
I could totally envision Shia as the least popular Robin. Shia would perfectly fit the bratty Jason and I would probably enjoy seeing him die in the hands of the Joker.
Robin (Tim Drake)-Taylor Lautner
First off let me say I hate Twilight but I really think Lautner would be an awesome Tim Drake. Secondly he is already trained and has the build. He's a pretty good actor and would be an ass-kicking Robin!!
Robin (Stephanie Brown)-Teresa Palmer
When I was searching for a pick I needed someone who was blonde and had the look of Stephanie and I think Teresa nails both of them with the added bonus of her hotness.
Robin (Damian Wayne)-Kodi Smit-McPhee
He is the best young actor out there and luckily he looks just like Damian and therefore is the perfect pick for Bruce's young son.
Batgirl (Barbara Gordon)-Emma Stone
Emma looks just Barbara and she looks just like Barbara. I did consider Kristen Stewart but I decided one Twilight actor was enough :P! Anyways Emma has the same colour hair as Barbara and the acting chops.
Superboy-Kellan Lutz
Kellan is built like a brick and has the perfect look for Superboy. He may not look exactly like Superboy but nothing too much for a make up artist cant handle.
Supergirl-Amber Heard
Amber looks exactly like Supergirl when she has blonde hair and although she is not the greatest actress, she could work on it and be a great Supergirl.
Powergirl-Elisha Cuthbert
Firstly there is no-one on earth who is young and with that size bust and secondly Elisha does have a decent bust but most importantly looks like Power Girl and can actually act!
Black Canary-Yvonne Strahovski
She's perfect imo. She's hot, has the look and the chops. Simples!
Huntress-Mila Kunis
She may not be the greatest actress on earth but she is improving and she has the look nailed. Plus she's hot!
Zatanna-Serinda Swan
I hate Smallville yet Serinda is a good actress who looks just like Zatanna and gave a good performance and I think she is fantastic for the role.
The Question-Keifer Sutherland
We all know Keifer is a great actor and this seems like an obvious choice as he would play the genius Vic who is also The Question.
Rorschach-William Fitchner
Although Jackie Earle Haley played the role perfectly, Fitchner would be a fantastic replacement. He looks like a damn physcopath! He's a great,seasoned actor who would own as the ass kicking Rorschach
Nite-Owl-Nathan Fillion
For this role I tried to pick someone who looked similar to the comic version of Nite Owl and Fillion is just that!
