Age: 23
Notable role: Grace in Short Term 12 (2013)

Despite her young age, Brie Larson has paid her dues. As a kid, she was cast in two quickly canceled series Schimmel (which never made it to air) and Raising Dad, and was dropped from the unaired pilot of Hope & Faith. She had small roles in teen movies until 2009, when she was cast in The United States of Tara. It was canceled in 2011. 

It's been a long time coming, but Brie Larson's raw talent is finally being recognized. Her latest film, Destin Daniel Cretton's Short Term 12, won the Grand Jury Narrative Feature Award as well as the Grand Jury Audience Award at this year's SXSW Film Festival. In it, she carries the film as a foster care facility supervisor coping with her own personal demons. Darker than any mainstream movie she's done before, namely Scott Pilgrim vs. the World and 21 Jump Street, the film proves that the fully realized Brie Larson has finally arrived.
