To me, there was an interesting movie to be made about two people who had been on that whirlwind romance and what happens after the fairy tale wedding. And this thought coincided or coalesced when I was at a wedding of a friend who got married to somebody that literally everybody in the congregation thought that you definitely should not get married to. This was the worst idea either of you have ever had.

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 think improvisation is really crucial in terms of making things feel real and authentic.

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.

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

It's incredibly easy as a director to be egotistical. Of course, it is because you have 200 people on set every day listening to your every word and whatever you say goes, and that can be slightly corrupting. And actually, to be a good director, you have to take ego out of it, because hopefully what you've done is surrounded yourself with brilliant people. Let them be brilliant and you just shepherd that and marshal that and hopefully guide it however you can, but definitely not to the extent that you're overbearing.

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
