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'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.

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.

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.

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.

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.
