'United States Of Tara' Star Brie Larson Heads To '21 Jump Street'

21 Jump Street” just a got a little more crowded.

Deadline reports that “United States Of Tara” star Brie Larson (who you might recall as Envy Adams in ‘Scott Pilgrim’) has joined Jonah Hill, Channing Tatum and Ice Cube in the film. The R-rated adaptation features a script by “Scott Pilgrim Vs. The World” writer Michael Bacall who had previously and excitingly described the pic as “John Hughes meets ‘Bad Boys,’” with “Cloudy With A Chance Of Meatballs” directors Chris Miller and Phil Lord at the helm for the story of “a couple of dudes who haven’t quite worked out their emotional issues with high school, who are returning to high school.” Larson will take on the role of Molly the female lead part Emma Stone was linked to last year, before she was cast in “The Amazing Spider-Man.”

“21 Jump Street” begins shooting in April and will hit theaters on March 16, 2012. No word yet if Johnny Depp will do a cameo, but we hope so, because that would kind of rule.
