Liam Neeson has joined Russell Crowe and Elizabeth Banks in the cast of The Next Three Days, which is shooting in the Pittsburgh area.

The Lionsgate project revolves around a woman imprisoned for a murder she claims she didn't commit and her college professor husband who decides to break her out.

Neeson's scenes, which are cameo in nature, see the actor playing a man who escaped from prison several times and wrote a book about the subject. He gives advice to the professor.

Paul Haggis (Crash) directs.
