I'd watch Hugh Jackman do just about anything... and we know he's good at the whole "forgotten / rediscovering his past" thing...
Babydol's right about Carth's voice, though. I remember swooning when playing Republic Commando, too.
However, that being said, I think I could get over it if it was done well...
And having seen Iron Man and Speed Racer this weekend, I actually have a little faith that Hollywood can get it right sometimes...
Robert Downey, Jr was highly impressive as Tony Stark, I must say. I wouldn't mind seeing him playing Revan either, even if he is a little old for it.
