Jacki Weaver, who received an Oscar nomination for her performance in Animal Kingdom last year, has joined the cast of Five-Year Engagement for producer Judd Apatow and Universal Pictures.

Although it isn't known what role Jacki Weaver will have, she joins a cast that already includes Jason Segel, Emily Blunt, Alison Brie, Chris Pratt, and Rhys Ifans. The story centers on Jason Segel and Emily Blunt's characters, who are finally about to wed after an extremely long engagement.

Nick Stoller (Forgetting Sarah Marshall, Get Him to the Greek) is directing from a script he co-wrote with frequent collaborator Jason Segel. Judd Apatow will produce alongside Rodney Rothman.

It isn't known when production will start on Five-Year Engagement yet.
