Dealmaking has been underway for months and is described as very complex, according to sources.

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 previously was attached to direct Interstellar and produce with Lynda Obst. It is unclear whether 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 multilayered nature of the story.

The filmmaker is repped by WME and Bloom Hergott.
