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.

I learned that I enjoy directing a lot more than I enjoy writing, which is interesting, because writing is lonely and infamous basically.

I like to foster an atmosphere on set of collaboration and openness and risk taking. The beauty is when you have such brilliantly talented people as I did in my cast, you definitely don't want to fetter them in any sense. You want them to be able to go out there and do their thing and feel confident in doing their thing, because ultimately I'm the person who gets the credit which is great.

You sit down in the morning on your own to write something. You get to the end of the day and it's not like you've cracked it and it's finished and it's done, because it can always be improved. It can always be changed. There is no right answer, so you can drive yourself crazy with just the expanse of infinite possibilities when it comes to writing.

I don't want to sound arrogant and say that I know everything about directing and I've got it cracked, but it was just all in all a joyous experience. To me, the key to directing, to be honest, is just surround yourself with brilliant people and let them do their thing

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.

I know what I want. I try and convey that at the beginning and set that out, but within those parameters, I'm very happy for them to experiment and try things and give it a go. To me, it's important.
