I haven't seen Forgetting Sarah Marshall but I hear it is surprisingly funny. Always a good thing for a comedy. The titular Sarah Marshall character is played by Kristen Bell. I don't think I've ever seen a Kristin Bell TV show or movie - unless I go see FSM between now and whenever you read this - but she definitely seems to be a pseudo-"it" girl right now. Beyond the obvious reason (i.e. she's a babe), here are two reasons why we love Kristen Bell:
1. She is a huge hockey fan (well Detroit Red Wings anyway) and had a crush on Chris Osgood when she was in high school. read her full NHL.com interview here.
2. She does a mean Princess Leia impersonation.
