In terms of the way the industry operates, the studio system was such its own thing. It's so different now that it's a globalized world.

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 think, because it's one of my favorite moments in [Charles Manson's Hollywood]. That series got a lot of attention and people talk about it a lot, but they tend to focus on the episodes that have more to do with the murder, Charles Manson doing something particularly weird, or Sharon Tate.

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.

I just think the David O. Selznick story is one of the great, epic stories of Hollywood history that nobody knows. Maybe one of the reasons why nobody knows it is because he wasn't a movie star.

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.

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