Mark Levinson: When I was first thinking about the film and just trying to think of any other science documentaries that did anything interesting, Nostalgia for the Light is one of the few I could think of—and it’s not even totally a science film—but it’s what I was aspiring to. It’s much more contemplative and philosophical.Part of the way you did that in the film was through getting the scientists to really open up, zoom out, and share their grandiose views on our place in the universe. How did you get scientists to share that with you?
You know, among themselves, they don’t talk philosophically that much. But they all think about it. If you give them the opportunity, and ask them the right questions, it turns out they’re really into it.

David Kaplan is a theorist at Johns Hopkins, and he was telling all of his family and friends that this giant machine was going to turn on and that it was going to be amazing and change everything—and so somebody finally told him that he should find some way to record it. I heard about it because I was in the fiction world at the time and was presenting a script to a bunch of investors, and someone told me about this giant experiment someone wanted to film, and that no one knew if it was going to work out. I thought this chance to use my narrative skills to tell this really interesting science story was really attractive. David wanted to capture something that felt authentic, and I could see that this could potentially be a dramatic film.

Roughly 500 hours. But then we gave everyone little HDV cameras to have some more confessional, personal bits, and then we also realized we could use this to fill in some of the physics so it felt like these characters are just talking to you, rather than some omniscient narrator explaining everything. And then CERN itself has an extensive media department that’s been filming 16mm films since the 1960s—it’s amazing. Somebody was cutting films together and overlaying them with jazz; there was another one that was this awesome sci-fi thing that was playing with horror and was really funny actually. Now they’ve developed it and it’s become more sophisticated, so I could count on them to get tons of footage for me as well. And then there are the archives! So when I say 500 hours, that’s what I looked at. I could have looked at more, but I’m human.Why did you leave physics in the first place?
It was not a good time for particle theory—it was sort of stuck at the time. I was actually extremely theoretical, to the point that I almost didn’t know any experimentalists. Even the LHC would have seemed too practical. What really appealed to me was the beauty of the mathematics and the abstraction. It was almost like pursuing art, and then it was around that time that I actually discovered art as well.

Well we were making a film anyways, that was for sure. After I got over the initial shock of the accident and thinking we might not be making a film anymore, then I realized we might actually be making an even better film. But we really didn’t know what the end would be—we were filming an experiment!How did you deal with the problem of scale in the film?
It is sort of ironic isn’t it? You’re asking the biggest questions, and you need to see the smallest things, and it requires the biggest machine ever built to study it. Part of it was having shots of the five-story high superconducting magnets, and then just showing the geography of the area—what a 17-mile loop really looks like. The animations helped to bring to life everything that’s invisible to the naked eye.You talk surprisingly a lot about art for a film that’s about physics. You even end with talking about the Werner Herzog film, Cave of Forgotten Dreams, about the first human cave drawings in southern France. Why did you make that such a focus?
It was extremely conscious. It was my life in some sense: I had gone from physics to art. I wanted the film to end with something bigger than just physics, and that’s what it’s all about—it’s all about the context, which is that this is a human pursuit.Was there any point while you were filming where you sort of missed that world, and—
Wondered if I made the right choice? You know, the very first time I went to CERN, the cafeteria is a very special place there. It’s an incredible international mix, and everyone’s relaxing, but they’re also really casually talking about physics. The theorists often all go to lunch together, and the first time I went with them I did have this really weird flash like, wow, I could have been here in exactly the same way, except I would have been here as a physicist talking in my natural habitat.But in the end, I actually feel I made the right choice. I think that I may have more impact on physics with this film than I may have actually had in physics. Even just from an archival point of view, we captured one of the most unique moments of discovery in our lifetime. This is my contribution to physics.
