Gotta love this from the Interstellar movie wiki:
In January 2013, Christopher Nolan entered negotiations with Paramount and Warner Bros. to direct Interstellar. Nolan intended to write a screenplay based on his own idea that he would merge with his brother's screenplay. By the following March, Nolan was confirmed to direct Interstellar, which would be produced under his label Syncopy and Lynda Obst Productions.Though Paramount and Warner Bros. are traditionally rival studios, Warner Bros., who released Nolan's Batman films and works with Nolan's Syncopy, sought a stake in Nolan's production of Interstellar for Paramount... In August 2013, sources reported that Legendary Pictures was in the process of finalizing an agreement with Warner Bros. to "finance 25 percent or more" of the film's production.
Wow, talk about someone (Nolan) writing their own ticket! Very much looking forward to this and hope it lives up to all it's $ and promise.
