Nolan to head into outer space?

Christopher Nolan is reportedly in talks to direct sci-fi drama Interstellar.

The Dark Knight filmmaker has apparently set his sights on the movie and is going through a "very complex deal-making" process, reported Heat Vision blog.

The time-travelling film, written by Christopher's brother Jonathan with its script inspired by Kip Thorne's scientific theories, sees a group of explorers travelling through a wormhole to "alternate dimensions".

Steven Spielberg was previously attached to direct Interstellar, but it looks like the Nolan brothers will reunite once again, following their previous collaborations on the Dark Knight trilogy, The Prestige and Memento.

Christopher revealed at The Dark Knight Rises UK premiere in July that he hadn't thought of his next move, saying: "I haven't figured out what I'm doing next."
