Says Deadline, as part of a larger feature on the directors who figured prominently into this year's Academy Awards voting:
"News also broke last night that The Dark Knight Rises helmer Christopher Nolan has focused his attention on Interstellar, which could only have happened after Spielberg decided it wasn’t a good fit for him. Spielberg set up the project in 2006 after becoming intrigued by Caltech physicist and relativity expert Kip S. Thorne and his scientific theory that wormholes exist and can be used for time travel. Paramount (after it bought DreamWorks) signed on a year later and set Jonah Nolan to write it. The Nolan siblings obviously work well together (Jonah hatched the short story that became Christopher’s first hit Memento, and they collaborated on two Batfilms and The Prestige).No stars, production start date or release date have been nailed down for the movie, and last we heard, Nolan still hadn't yet finalized his deal.
Insiders tell me that Christopher Nolan is writing a script that merges an original idea of his with the script that Jonah wrote. It will retain the title Interstellar, and the ambition for the project is a film that will depict a heroic interstellar voyage to the farthest borders of our scientific understanding. If it all pans out, he’ll direct. Nolan’s unofficial home studio, Warner Bros, has been kissed into the deal as a co-production partner with Paramount, and Christopher Nolan and Emma Thomas are producing with Lynda Obst. Jordan Goldberg is joining as exec producer alongside Thorne, who’ll remain on as technical consultant.
