What do you get when you sit down two of the coolest sci-fi filmmakers to chat about one of the coolest sci-fi flicks of the year? This, and it’s awesome.

At some point last month, Interstellar director Christopher Nolan (Dark Knight trilogy) participated in a post-screening Q&A of the film with Rian Johnson (Looper, Star Wars: Episode VIII) at the Aero Theater in Santa Monica. An audio recording of the interview has finally leaked out, and it’s just as great as you probably imagined. It's 30 minutes of pure geek gold.

If you enjoyed Interstellar, admire Nolan or like Johnson, it’s a must-listen. While he doesn't really delve into his upcoming Star Wars duties, Johnson keeps the discussion moving in interesting directions. And Nolan touches on everything from secretly stunt-casting Matt Damon as Dr. Mann to the film’s strange genesis that started out with Steven Spielberg originally attached to direct a very different version of the film.

Nolan reveals how the script started as a way to tell the “most outlandish elements of science fiction based on reality,” but once he took over he combined those ideas with some other scripts he had been working on. That’s kind of obvious, and it puts the entire scope into perspective once you realize Nolan was basically trying to look at these heady themes and co-opt those concepts into an existing script. Not to say it's disjointed, but it puts the story into a better perspective.

He also touches on their approach to the spaceships, saying they built most of them fully enclosed and shot inside those closed sets to make it seem as realistic as possible. Also: Weirdly enough, they actually made money by selling the corn planted for the film. Which kind of makes sense, considering they seeded an astounding 800 acres of corn to set the scene around Cooper’s house.

Check out the full audio of the Q&A below and let us know what you think:
