You may know her best as Kate the rebellious daughter on United States of Tara. I remember her fondly in Remember the Daze and Just Peck.And of course, Scott Pilgrim. Her first TV series was Schimmel back in 2000. Unfortunately, it was put on hold so long it never aired on Fox. Some say she should play Jennifer Lawrence's sister in a movie. She toured with Jesse McCartney when she was younger. Brie Larson.
