Matt Damon Is Last-Minute Addition To Christopher Nolan's Interstellar

Even as we still try to sort out a rumor that he's getting ready to return as Jason Bourne, Matt Damon may have lined up another project with another super high-profile director-- and one who we thought was totally done casting his next film. The Playlist writes that Damon has joined the cast of Interstellar, the new film from Christopher Nolan that kicked off production earlier this month, and already with more than enough stars to fill a spaceship or two.

As with every single other person who has joined the cast, there's no details on which role Damon might play, and it's worth noting that there's no confirmation from a studio or personal reps in The Playlist's report, so it's entirely possible this won't happen.What's curious, though, is how Damon could possibly find room for a role in a film that clearly already has its main cast in place. Is he really taking on a tiny supporting part? Is it more like a cameo? Oooh, maybe it's that crossover film between Elysium and Interstellar that we've all been waiting for! (OK, maybe not that last part).

At the very least, Damon would have plenty of good company aboard the spaceship that's at the center of pretty much all we know about Interstellar, based on this plot description: "The new script chronicles the adventures of a group of explorers who make use of a newly discovered wormhole to surpass the limitations on human space travel and conquer the vast distances involved in an interstellar voyage." Matthew McConaughey plays what we believe to be the lead character in the film, with Anne Hathaway and Jessica Chastain right next to him, and a massive supporting cast that includes everyone from Michael Caine to The Butler's David Oyelowo. Maybe Matt Damon has had "work with David Oyelowo" on his bucket list, and this was the best way to cross it off?

It's hard to figure exactly how this casting makes sense, but given how little we know about Interstellar, anything is possible. The mystery will remain in place until Nolan is forced to reveal something for the sake of a teaser-- maybe around Christmas, if we're lucky?-- and all will be revealed when Interstellar arrives November 7 next year.
