Jessica Chastain To Join Hathaway And McConaughey In Nolan's INTERSTELLAR?

I hope she is ready for some heady, heavy like gravity, sci-fi as Nolan's film should be about a group of explorers traveling through worm holes. I say should be because Christopher has never been one to willingly share details about any of his projects. But as you recall when we first got wind of this project we knew that his brother Jonathan's script is based on a treatment about traveling through wormholes by astrophysicist Kip Thorne. And those kind of guys don't scrimp on the details.
