Community has made another A+ hire.

The NBC comedy, which has already recruited James Brolin, Malcolm McDowell and Matt Lucas for Season 4 stints, has tapped the comically gifted Brie Larson (United States of Tara, 21 Jump Street) to guest star, TVLine has learned exclusively.

The actress will play… a character whose identity is being kept under lock and key. All we can confirm is that Larson will appear in this season’s seventh episode, which finds Dean Pelton planning a “Sadie Hawkins” dance at Greendale.

Britta, meanwhile, plans a competing “Sophie B. Hawkins” dance in protest — there’s just one problem: Britta has confused Sophie B. Hawkins with, um, Susan B. Anthony.

Community is set to return on Oct. 19 at 8:30/7:30c.
