A24 has acquired U.S. rights to the upcoming family drama “Room,” starring Brie Larson.

The film, based on Emma Donoghue’s 2010 novel, is set to shoot in the fall with Lenny Abrahamson directing.

Ed Guiney is producing. Andrew Lowe will executive produce for Irish production company Element Pictures and Tessa Ross, Sue Bruce Smith, and Rose Garnett will

“Room,” which came out in 2010, is told from the viewpoint of a 5-year-old boy being held captive with his mother in a small room. The book has sold more than two million copies worldwide.

A24 negotiated the deal with UTA Independent Film Group, which is putting together the financing alongside Element Pictures. FilmNation is handling worldwide sales.
