Huge fan of Bale as Batman, but he is replaceable. The toughest act to follow is Rob Downey as Tony Stark. He's just perfect for the role.

Where's Michael Keaton as Batman? But seriously, how is this even fair? Robert Downey Jr is Ironman

The guy who played J Jonah Jameson in the Spider-man movies. That's as perfect a casting as you're ever going to get.

Who are the goofs that picked that nerd Toby McGuire as Spiderman? He singlehandedly made me hate Spiderman as a character...I can't even watch the new ones even though it's not him anymore.

But I'd go with Downey Jr. He kind of has the whole narcissistic, rich, don't give a fuck thing down pat...which works for Iron Man since he has no actual powers, just tons of money and technology.

Also Christian Bale as Batman isn't half bad.

Ron Perlman as Hellboy.
