Ok lets get started.
Michael Sheen as The Joker
After I saw Sheen in Tron I immediately thought this guy could have a crack at the Joker.
Eric Bana as Hush
I really like Bana in all his movies especially Troy and Star Trek. I think this would be a very good role for him because Hush is just his type of role he is made for.
Ellen Page as Harley Quinn
I really liked Ellen in Inception, and I think she is fully capable of playing Quinn.
Aaron Eckhart as Harvey Dent/Two Face
I really thought Eckhart owned the role so I decided to keep him the same.
Phillip Seymour Hoffman as The Penguin
Hoffman is an amazing actor. He won an academy award for his role as Capote which was fantastic. He is a great villain in Mission impossible 3, and I think he would be great as Penguin.
Robert Downey Jr as Clayface
I think we can all agree that RDJ is a great actor, and very good at portraying roles maybe not exactly thought he could play like Sherlock Holmes(which he's great in). I think He would be best as the Matt Hagen version.
Leo DiCaprio as Black Mask
I can only see DiCaprio in this role.
Tom Hardy as Hugo Strange
I chose him because of the rumors mostly on this pic in which he really resembles Hugo, and because he's a fantastic actor.
Ed Norton or Brad Pitt as Firefly
Ed Norton Is amazing in almost every movie I've seen him in. Brad Pitt is just pure awesome in Fight club in which he portrayed Tyler Durden which is the best movie character I would say ever has been on screen, and I think Firefly is a little bit similar to that role.
Andy Serkis as Scarecrow
He is great as Gollum in TLOTR series and he's a fan favorite.
Michael Clarke Duncan as Killer Croc
Amazing actor in Armageddon and countless other films. I think his voice would be great for Croc.
Collin Farrell as Deadshot
Farrell is very good in Pride and glory and Swat. I think he would be a perfect Deadshot (sorry Lee I think He' better than Hardy).
Kate Beckinsale as Catwoman
I hate Catwoman, but Beckinsale could play the role
Randy Couture as Bane
He has the physical capability and I don't think he would have to do much acting.
Sam Witwer as Anarchy
I dont know to much about Anarchy, but from what I've read about him I think Witwer could play him.
Thanks for reading Ill have Pt 2 out in a week or so.
