Biggest accomplishment this year: The fourth season renewal of NBC's Community
Alison Brie's days as an underground success is coming to a close. Her standout performances this season as Annie on NBC's much-loved but little-watched Community and Trudy on Mad Men have helped propel her to wider recognition. She'll be appearing in the independent The Kings of Summer, which will be coming out in limited release on May 31. Interviews with Brie reveal a person who is refreshingly quirky and sure of herself, with subjects ranging from her freestyle rap skills to anecdotes about hooking up with a gay male friend all being in play.
