9. Kevin Sussman: Now
While the character of Stuart may have social challenges, the actor who plays him is a normal guy. Sussman came into the role with a decent resume. In 2001, he was in the movie AI Artificial Intelligence as a super nerd, and before that in the movie Almost Famous as Lenny. He’s kept busy on other shows like CSI and Children’s Hospital, but also on movies like Hitch and Burn After Reading. Sussman may make a paltry $50,000 for episodes of The Big Bang Theory, but he’ll be okay when the show ends.
