Christopher Nolan Reluctantly Opens Up About 'Interstellar'

The secretive director teased a family-friendly tone at CinemaCon.

CinemaCon, a convention where studios and filmmakers show off upcoming features to theaters owners, is going on right now, and a lot of info about highly anticipated movies, like "50 Shades of Grey," has made it onto the web.

The "Interstellar" presentation, however, was light on specifics, since "telling people stuff" isn't exactly Christopher Nolan's M.O., but the secretive director did open up more than ever before about his outer-space epic.

In a conversation with Todd McCarthy, the film critic for The Hollywood Reporter, Nolan discussed very broadly who he hopes to reach with "Interstellar" (everyone) and what he thinks about the McConaissance (he totally called).

One of the more exciting things about what Nolan said is that he wants to achieve with "Interstellar" is to return the "family film" to its former glory, when movies like "Star Wars" could have a wide appeal without being backed into a corner with "kid stuff."

"I grew up in an era that was a golden age of the blockbuster, when something we might call a family film could have universal appeal. That's something I want to see again," he said. "In terms of the tone of the film, it looks at where we are as a people and has a universality about human experience."

That last quote might literally be the most vaguely describe theme ever. Bravo, sir.

On the Matthew McConaughey front, Nolan said that it was the actor's seriously underrated turn "Mud" that convinced the director that he could pull off the lead in "Interstellar."

"['Mud'] showed me a side of Matthew's capabilities that I never knew was there. It was a transformative performance. From when I first saw it, I had an inside track on how great he could be," Nolan said. "I needed someone who is very much an everyman, someone the audience could experience the story with. He's just a phenomenal, charismatic presence in the movie. His performance is shaping up to be extraordinary."

"Interstellar" opens in theaters on November 7.
