The 'Dark Knight Rises' director is negotiating to board the sci-fi project written by his brother and longtime collaborator Jonathan Nolan With his Batman trilogy now complete, Christopher Nolan has found his next project. According to multiple sources, Nolan has set his sights on a sci-fi project titled Interstellar, which he is in talks to direct and produce. The project involves time travel and alternate dimensions in a story that sees a group of explorers travel through a wormhole. The script is based on scientific theories developed by a Kip Thorne, a theoretical physicist, a gravitational physicist and astrophysicist at Caltech. Sources say that dealmaking has been underway for months and is described as very complex. Interstellar is set up at Paramount but would be made by both Paramount and Warner Bros., where Nolan and his Syncopy banner are based and for which he has made the three Batman movies as well as Insomnia and Inception. (The Prestige was made for Disney.) The script for Interstellar was written by Jonathan Nolan, Chris' brother, who worked on The Dark Knight Rises and The Dark Knight, as well as Prestige. Jonathan Nolan (known as Jonah) also has a "story by" credit for Memento, Chris Nolan’s breakout movie. Steven Spielberg was previously attached to direct Interstellar and produce with Lynda Obst. It is unclear if Spielberg will remain involved, especially considering the director's planned next movie, Robopocalypse, was delayed indefinitely on Wednesday. Regardless of how a deal shakes out, Interstellar has all the elements that seem to attract Nolan. Apart from his brother’s involvement, there is the complex and multi-layered nature of the story.
