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.

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

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

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.

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.

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.

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.
