Making a movie about both real people and the fake characters they played can be tricky—just ask Dylan Everett. For his roles as the actual Mark-Paul Gosselaar and the fictional Zack Morris, Everett had a lot of research to do because, believe it or not, he had never even seen the original series before. (Give him a break—he's Canadian.) ''It was always one of those shows people compared things to, so I was aware of it,'' the actor says. So how did he manage to balance playing both characters? He didn't. ''I really wanted to show Mark-Paul struggling with his identity.'' — Jake Perlman
