Hit the jump for more on each casting announcement.

First up from Deadline comes word that Riseborough will stars as Laura in Birdman, a dark comedy that centers on a has-been actor (Keaton) who gained fame for playing a superhero, and who now attempts a career revival by directing a Broadway play, but finds his efforts made all the more difficult by an egotistical lead actor.  Riseborough will next be seen opposite James McAvoy in Welcome to the Punch, followed by Oblivion with Tom Cruise.

Variety reports that Heathcote is set to join Lawrence's untitled rom-com that focuses on a "creatively washed up, divorced and broke former award-winning screenwriter (Grant), who is forced to take on a job teaching screenwriting at a small college."  Heathcote will play one of his students.  She's next expected to film the high school horror/thriller The Curse of Downers Grove, written by Bret Easton Ellis.

Also from Variety comes the latest addition to This Is Where I Leave You, with Stoll joining the cast.  He'll play Bateman's brother as part of a dysfunctional family which is forced to spend a week together under their childhood home after their father wills it on his death bed.  Stoll will next be seen in Decoding Annie Parker and Non-Stop with Liam Neeson.
