She went on to play Catherine Keener's daughter in The 40 Year-Old Virgin (2005), then landed a regular role on NBC's ER as Zoe Butler for one season.
Back on the big screen, she played substantial roles in Big Momma's House 2 (2005), Charlie Bartlett (2006) and The House Bunny (2007). She was nominated by the International Press Academy for a Satellite Award for her performance in Nick & Norah's Infinite Playlist (2008) and appeared opposite Woody Harrelson and Sandra Oh in the film Defendor for Sony Classics. In Daydream Nation (2011), she played the lead character.
Dennings plays Darcy in the movie adaptation of the comic book Thor (2011), directed by Kenneth Branagh and starring Natalie Portman and Chris Hemsworth.
