Christopher Nolan’s space epic Interstellar just opened over the weekend, prompting the famously secretive director to emerge from the shadows of the Nolancave and speak to members of the press. Over at The Daily Beast, Marlow Stern spoke to the filmmaker about far-flung topics, including the movies he’s made, the movies he hasn’t made, and the movies he might make.

Some key excerpts below:

On the new Star Wars movie

“As far as whether or not I would have ever done it, the truth is I think I’d be afraid to touch it! [J.J. Abrams is] boldly going where he went before in Star Trek, and it takes colossal balls. I’m a lot more comfortable trying to do my own thing than carrying the weight and expectation of the entire world—particularly 40-somethings like me who live and die with each new bit of information about Star Wars.”

On plot holes

“My films are always held to a weirdly high standard for those issues that isn’t applied to everybody else’s films—which I’m fine with. People are always accusing my films of having plot holes, and I’m very aware of the plot holes in my films and very aware of when people spot them, but they generally don’t.”

On the physics of Interstellar:

“There have been a bunch of knee-jerk tweets by people who’ve only seen the film once, but to really take on the science of the film, you’re going to need to sit down with the film for a bit and probably also read Kip’s book.”

On the future:

“I’m very worried about our future in a lot of ways. I think nuclear weapons are still an enormous threat and tend not to get talked about very much. There are obviously massive environmentalism issues that need to be addressed. But I am an optimist, and I think this film is very optimistic. When you look at the world these characters are living in in the beginning, it’s not a post-apocalyptic Mad Max scenario. It’s bucolic, agrarian, and a simple way of life, and people are coping.”

On his Dark Knight trilogy and the possibility of directing another superhero film:

“I worked on it for a long time—almost 10 years—and had an incredible experience. It was totally fulfilling, so I’m done with that part of my life.”

On making a Bond movie:

“I love James Bond and I’ve talked with the producers over the years, but nothing’s ever worked out. They do a great job—they don’t need me right now, and Sam [Mendes] is an extraordinary talent.”

On whether he’ll ever go back and make his Howard Hughes biopic:

“I think it’s the best script I’ve ever written, and I had a really wonderful experience writing it. Yeah, it was a frustrating experience that the other movie got going. Will I revisit it? I have no idea.”
