Steve Levitt was a bad choice
This actor was a bad idea to play a wimpy character. It seemed like he did have to pretend to be one. His dialogue is simplistic, stupid, and cartoonish.
He calls Thor: "Big Fella," at one point which sound incredibly more pathetic. This is why Bill Bixby was cast as Banner, so Banner didn't resemble a nerd, had some star and sex appeal.
Steve had neither.
I'm sorry I'm critical here but this guy's performance in this film really naws on me.
