20 Actors You Totally Forgot Were In Comic Book Movies

2. Sam Rockwell

The Movie: Teenage Mutant Ninja Turtles (1990)

Who He Played: The "Head Thug" whose gang April caught stealing, sold cigarettes and other things.

Why You Forgot: Sam Rockwell's appeared in numerous films ranging from dramas like The Green Mile and Moon, comedies like Galaxy Quest, other comic book films like Iron Man 2 and even the upcoming remake of Poltergeist, but his career all started thanks to small early roles like his spin in the original live-action TMNT. It's been 25 years since its release and Rockwell has come a long way, but it doesn't tarnish the surprise or fun of seeing him pop up one bit.
