The only Sundance [2011] film about cults that could actually have life as a cult film, THE WOODS has the greatest comic insight into why our current culture might inspire a search for meaning in the first place.

For me, the Dennis Wilson story is a quintessential You Must Remember This story because it's one of these stories that people never talk about, don't really think about, and it's forgotten within this major thing that is thought to be this cataclysmic event of the 20th century.

You read these stories of people who were in Hollywood in the late '60s. After they found out about the murders, everybody was like, "Have you met [Charles] Manson? Have you been to that ranch?" In some way, everybody felt connected, but what was it like for people who really were connected.

Now I'm in a situation where I have to plan very far ahead because there are people who are selling ads, so I have to really know what I'm going to do months in advance. If something's taking me a little bit longer to research, that's not okay. I can't take longer. I have to just get it done.

I have a degree in cinema studies and the big paper I wrote at the end of that was about Judy Garland and Liza Minnelli. So I thought that I knew quite a bit about Judy Garland, but I read in passing that the Stonewall riots were a reaction to her death and I had never really read enough to know what that meant or how that could be true. I was interested in that I knew so much about Judy Garland, but I really didn't know this story.

The thing that breaks my heart about [Dennis Wilson] is that he was very naïve from the beginning to the end.

There's a fantastic, thousand-page book by David Thomson about [David O. Selznick]. Again, it's not the best argument or the best advertisement for his story, because most people aren't going to read a thousand-page book. But I feel like the rise and fall and the work [Mayer] produced - not just the movies, but the memos, the volume of writing - he's just so passionate, and that's really exciting.
