Chris Nolan is going hard scifi with his next movie Interstellar

Christopher Nolan is finally reaching for the stars! He's in talks to direct and produce Interstellar, based on a script by his brother Jonathan. Sez The Hollywood Reporter:

The story involves time travel and alternate dimensions and sees a group of explorers travel through a wormhole. The script is based on scientific theories developed by Kip Thorne, a theoretical physicist, gravitational physicist and astrophysicist at Caltech.

That's all we know for now, but a hard sci-fi flick by Nolan? We'll be keeping a close eye on this one.
