As a performer, I could be like, "I don't want to leave that in there." But as a producer, I have to leave it in there.

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.

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.

Between the action sequences, the pleasure lies in observing impeccably dressed Brits exchanging barbed witticisms - making it, basically, Downton Abbey with cyber crime and shower sex.

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.

I really feel like I could do anything if given enough time.

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.
