Him or Henry Cavill as Superman

No. No. No.

Uhhh....no. Cute guy but no.

Bwahahahaha. This is so funny I had to comment. Kevin is cute but the farthest thing from a superhero as you can get. He might be able to play a Robin but he's probably still to "cute" for something like that. He should spend a few months in the gym, get a buzz cut and take some photos. That would be a good judge of whether something like that would ever be possible.

No hell no. It would resemble a parody. He can't play most of the named superhero or supervillain, but if he has a chance, he should go for Robin or The Riddler.
