Julia Stiles is said to be joining The Silver Linings Playbook.
The award-winning Dexter actress is the latest addition to the cast, which already includes Bradley Cooper and Jennifer Lawrence, reported Deadline.
Chris Tucker is also thought to have "closed his deal" to make his acting comeback in David O Russell's big-screen adaptation of Matthew Quick's novel. It would be his first acting role since 2007's Rush Hour 3.
Bradley is on board to play a depressed teacher who falls for Jennifer's character. Julia - who starred in The Bourne films - would be cast as Jennifer's older sister, while Chris is set to be Bradley's best friend Pat.
Production on the drama is scheduled to begin soon in Philadelphia.
