Rupert did a great job tapping into his dark side in Deathly Hallows, so maybe he could pull this off!
Here's what he had to say about it:
“Being in Harry Potter was obviously amazing, but I want to move away from the whole Ron Weasley thing now."
“I really want to play a baddie in a Batman film.”
Probs too late for him to get into The Dark Knight Rises, but maybe the next one as The Riddler?
What Batman bad guy do U think Rupert could play?
