Period costume films are fun to discover, but they're not relatable. It's more, 'Wow, that's cool - did it really look like that back then?' Whereas with a comedy, you're like, 'Yeah, that's me, that's my friends.' No matter what, I want people to relate.

So many of my friends have always been women growing up... I always feel slightly more comfortable around women because with guys in general there's always more of a danger zone... it's very aggressive sometimes the way guys act with each other, putting each other down and calling each other names, so I was always too sensitive for that and used to hang out with the girls. And they were always really funny to me.

Women's humor seems to be a little more supportive. It's just kind of trying to make the other one laugh through funny voices and kind of talking about other people. I respond to that. I feel less like I'm going to get beat up in a room full of women than I do in a room full of guys.

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.

That's the thing with women's movies - there's so much about kind of catfighting. And my experience is women aren't - look, we all get in fights with people, but it's not that face-to-face aggression.

When guys see a movie starring women, they go, "That must be filled with these characters I see in these movies who are such a drag." And that's just bad for everybody.

I just love Kate. [Bieber], to me, is one of the funniest impressions because it's so all encompassing. It's like a total body and soul impression. But that's Kate. Every character she does is that way.
