Why? Because he has cast Will Smith and son Jaden Smith in his next film.

As announced Monday by Sony and noted by Entertainment Weekly, the Smith duo will star in Shyamalan’s untitled sci-fi movie about a father and son attempting to navigate a desolate Earth after their ship crashes on the abandoned planet 1,000 years in the future.

Wait: The twist is that Will and Jaden Smith are actually aliens who wind up making crop circles on a post-apocalyptic Earth, right? No, no — the twist is that they’ve actually been dead ever since Earth’s demise 1,000 years ago.

Honestly, it doesn’t matter. The movie will make millions of dollars because Will Smith is box office gold. And that will make Shyamalan bankable again, which will mean he can make even more thrillers and sci-fi-ish movies with endings that theoretically we totally don’t see coming.

Just giving you a head’s up now so you’re not surprised when this all happens in 2012 or 2013, after the film comes out.

P.S. I seriously hope Shyamalan shoots this one in Philadelphia. That way Will can finally ditch Bel-Air and come back to West Philly.
