5. Dan Byrd
Dan Byrd is the guy you see on TV who you wish you could have been friends with in high school. You might not recognize his name but you'd recognize his face as the first guy Emma Stone pretended to sleep with in Easy A or the woefully nerdy son of Courteney Cox on TBS's Cougartown. With bit parts in a number of movies and recent roles in quite a few TV shows including Boston Legal, Greek, Heroes, and Suburgatory, he has already shown the world his style- he's witty, effortless, and deviously sarcastic, not unlike Bill Murray's character in Ghostbusters. In a movie world where ghosts are attacking New York City and a bunch of guys in a revamped, white Cadillac limo are our only hope, Dan Byrd is exactly the kind of guy you'd expect to see get out of that car. He's an everyman with a natural sense of humor and the potential to carry a hilariously dark franchise like this one.
