Christopher Nolan‘s Interstellar has a stellar cast that is comprised of Matthew McConaughey, Anne Hathaway, Jessica Chastain, John Lithgow, Casey Affleck, Topher Grace, Ellen Burstyn, and Michael Caine.

Now you can add Matt Damon to that cast. The Playlist reports that the actor has signed on for a very small role in the film. In fact it is so small that he will only be on set for two weeks out of the four month shoot. The film centers on a group of space explorers who utilizes a newly discovered wormhole to stream across vast distances in an instant. Like almost of the roles in Interstellar, Damon’s role in the film is being kept under wraps.
