Wahlberg was first attached to the film that would see him reunite with The Fighter director David O. Russell in June. It was reported last month that Jennifer Lawrence was signing on to play Wahlberg's love interest in the movie.
However, production on The Silver Linings Playbook had to be pushed back due to Lawrence's commitment to The Hunger Games, which reportedly forced Wahlberg to drop out of the film. Deadline reports that Cooper will replace the Fighter star.
Cooper will play a man who is forced to live with his mother after leaving rehab for attempting to commit suicide. Lawrence portrays his neighbour.
The Hangover actor is currently shooting The Place Beyond the Pines opposite Ryan Gosling.
The Silver Linings Playbook is expected to begin shooting in the fall.
