Tony Scott may have only signed on to direct a movie version of Mark Millar and Steve McNiven's Batman-gone-bad comic Nemesis, but the Scottish scribe is already talking casting. As you might expect, he's aiming high.

With Nemesis, you’ve got two great roles for two A-list stars... The thing is, one guy has to be as good as the other. You’ve got Holmes versus Moriarty here or Batman versus The Joker, so each one has got to be a $20 million actor, really. I think you could go for the A+ list and get Johnny Depp as Nemesis and Brad Pitt as Blake Morrow.

Millar was holding court on the Nemesis casting with Empire Magazine, and went on to explain his choices: Depp is "a cross between Heath Ledger and Christian Bale" and "goes slightly crazy in his roles," while Pitt gets the imaginary gig because of his body: "It’s got to be somebody who can take a punch. You couldn’t really get anybody who’s too cerebral. He’d have to be a very physical actor so it would need to be a Pitt. Or maybe even a Liam Neeson."

Millar also went on to say that the plan is to film the movie next year, because of the story's timeliness. Or maybe just to not get caught too far behind Christopher Nolan's next Batman movie.
