I'm the biggest proponent of test screenings now. There's two ways to face test screenings. For dramas, I don't know if I would rely on them as much, although I still think you need them, because you're making a movie for an audience at the end of the day. But with comedy... You could go through a script or anything I ever worked on, where you go, "This is hilarious," and you put it in front of people and you get nothing. And then the other side of it, is something you're like, "I think this is really stupid," and it gets a giant laugh.

The good thing is that I really think that American television is in kind of a second golden age. Even though there's a lot of reality and all those contest shows, which aren't my kind of shows, the scripted stuff that's going on is so good right now because of basic cable. Everyone has stepped it up and realised that people like quality.

I'm kind of a failure. I mean, I'll be honest. I'm successful in that I'm getting to work on great stuff, but I think I'm a failure in all the personal stuff that is most important to me.

Where there seems to be a difference between guys being nuts and women being nuts is that guys are much more open in calling each other on stuff; lots of insults and dirty names. Whereas women will talk frankly and honesty, but there also seems to be more passive aggressiveness.

Any ensemble - they didn't call it "the all-male Expendables," for example. But it's Hollywood's fault that people say that, because there have been so few movies that have allowed women to have these leading roles, so that's Hollywood's fault.

I think things go wrong when there's not a very specific plan and specific emotional roadmap. You need to know what a scene needs to get across, and what story point that needs to be advanced, whether it's discovering someone for the first time or whether it's seeing a relationship get strained. What I do as a director is really create a safe environment that everyone can feel very comfortable in and experiment within so that they don't hold back anything.

In a perfect world, I'd love to make 90-minute movies, but for me, a movie needs to be as long or short as it can sustain itself.
