10 Typecast Actors Who Will Always Be "That Guy/Girl"
If you can think of a movie with a mature Adam Sandler performance, you've done better than us.

10. Michael Cera - The Awkward Teen
One day, perhaps, Michael Cera's face will stop looking like a teenager, and maybe then he'll be able to find other types of roles that suit him. But right now, he's 26, and can't seem to escape being constantly cast as the painfully awkward high school or college student. Just part of the curse of having a perpetual baby face, we suppose. People used to talk about getting Cera and Jesse Eisenberg confused, but while Eisenberg has taken roles that allow him to graduate from high school and challenge himself as an actor, Cera seems...stuck. Maybe the real difference between the two actors was that Eisenberg could play the awkward teenager, but there was also a strange sort of charisma (his detractors might say arrogance) that gave his characters depth. At the end of the day, maybe all Michael Cera really has going for him is the halting, fumbling delivery of that very specific shtick. It's sort of cute when you're a teenager, because what teenage guy doesn't struggle to find the right thing to say around girls, but when you're approaching thirty, it makes people kind of wonder if there's something wrong with you.
