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

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

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.

And then, movie-wise, I'm writing a couple of things. They're all comedies. It's the only way I know. I'm also being sent scripts, which is really nice, kind of off the back of this, so I don't necessarily have to generate my own stuff. I'm just looking for something that's explosively funny and relatable in equal measure.

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.

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.
