Everyone loves the Batman Beyond franchise. Bruce Wayne is elderly and retired, coaching young Terry McGinnis in how to be Gotham's Dark Knight. There has been talk lately of creating a live-action film based on this show and here's who I would cast in it!
Terry McGinnis/ Batman - Robbie Amell
Robbie Amell is a huge self-confessed Batman fan and has actually expressed interest in portraying Terry McGinnis. Robbie's incredible talent with superhero roles has already been demonstrated by his role as Firestorm on the CW's hit show The Flash.
Bruce Wayne - Kevin Conroy
Kevin Conroy is pretty much the most iconic Batman voice ever. The guy basically IS Batman. An entire generation grew up knowing him as the voice of the character, and I feel that it would be unfair to deny him the opportunity to play Bruce Wayne in live action.
Maxine "Max" Gibson - Zoe Saldana
Zoe Saldana is an incredible actress. If you need proof of that, look no further than Marvel's Guardians of the Galaxy. Zoe's Gamora can kick tail with the best of them, but she's also got some major sass and a sensitive side to her as well. As such, I think she would make an amazing Maxine.
Derek Powers/Blight - Hugo Weaving
I can think of no better actor to portray corrupt businessman Derek Powers than Hugo Weaving. After roles like The Matrix's Agent Smith and Captain America: The First Avenger's Red Skull, I think it would be interesting to see Hugo Weaving take elements from both of these performances in order to play Derek Powers and his supervillain identity of Blight.
Paxton Powers - Armie Hammer
Armie Hammer is one of Hollywood's greatest leading men. After roles like The Lone Ranger and The Man From U.N.C.L.E., Armie Hammer has shown that not only can he handle himself as a fighter, but he also has a more subtle charming side to him as well, both of which make him an excellent choice for the role of Paxton Powers.
