I think actors like to be directed. Actors like to know where they're headed and what they want, so I'm very encouraging.

I've been on lots of film sets. I've produced films and written films and been around, so it wasn't my first rodeo in terms of that stuff. Nothing particularly surprised me, I have to say. I came in and I enjoyed the first day and I enjoyed the last day.

It's tough to make funny films. And the truth is, with this process, especially if you write your own movie, then you're giving three years of your life to it. And so, I just have to be sure that when I embark on it that I'm happy to think that in three years' time I'm going to be sitting in a room on the tenth floor of an odd office building at Ginsberg Libby talking about it. So I'm keen not to jump into it too quickly and just make sure it's something that I really want.

So, as opposed to getting people in to read the script and read scenes with me, what I wanted to do was sit down and chat to these people and just say, "Okay. Do you share my sense of humor? Do you understand what this film is getting at? Do you know the tone that we're trying to get to?" And it was interesting.

In terms of magnifying it and making it plausible, I'm a great believer in truth in comedy.

With directing, your day is done. When you hit seven o'clock, it's "Cut." That's what it is. For better or worse, that's what you've got and you have to make that work, and there's something incredibly liberating about that because you can't torture yourself. You have to focus on the moment, and you have to embrace every second and opportunity and maximize that, whereas with writing, there's no imperative there. You just amble along.

My casting process was slightly different and slightly interesting insofar as I knew everybody could act. That's something you've seen. You know people can. You've seen them on the screen and you think either they're a good actor or a bad actor. So that's not the point. What I wanted to do was find people who I thought would have a similar comic sensibility.
