To me, the best projects are the ones where you have a pretty good idea of what the spine of it's gonna be, but then all sorts of things happen that you could've never predicted, and those are the magic moments of the films.

Of course no documentary is completely 'objective.' Every decision you make - who to interview, how to edit, where to hold the camera - imposes a point of view on the film.

When you are interviewing someone, never let your camera person turn off the camera. The second you turn off the camera, they'll say the magic thing that you'd been looking for the whole interview. People want to relax after the performance is done. Don't be afraid of awkward silence. That is your friend.

I'm looking for a charismatic character - somebody who you just want to look at and listen to and whom the camera likes. I'm also looking for a narrative arc: Something is going to happen, and there will be a question that will make you wonder what happens at the end.

I never heard about tefillin. I was unfamiliar with the deep history and ritual of being an Orthodox Jew. Before you get out of bed, you say a prayer, and then you get out of bed, say another one.

A lot of stuff doesn't faze me. I think it's because I was brought up in a small town, and normally, when you're from a small town, when you see a famous person, you'd be like, 'Oh my god. This never happens,' but I've always kind of been like nonchalant.

The overarching conventional wisdom - what everyone from government experts to my French girlfriends take as articles of faith - is that restrictive diets generally don't make you healthier or slimmer. Instead, it's best to eat a variety of high-quality foods in moderation and pay attention to whether you're hungry.

I went to church as a kid, but it was as much a social thing as anything going to the youth group with the other kids and whatnot. It wasn't until I got out of college that I got on my own religious trip and started finding other things out there as well as philosophies. I've kinda been on my own spiritual path since then.
