Brie Larson has been cast in Batman star Joseph Gordon-Levitt's directorial debut.
The 22-year-old actress and singer - who was last seen in the 21 Jump Street film - will play the sister of Joseph's character in Don Jon's Addiction, reports Variety.
Joseph, who has been directing short films for several years, penned the tale about a modern day porn-addicted Don Juan and will also star in and direct the movie.
The 31-year-old's character meets an older widow (played by Julianne Moore) and decides to try to become a nicer and less selfish person.
Rampart star Brie also joins Scarlett Johansson, Rob Brown and Tony Danza in the film.
