Irvine Welsh as uncle Tommy Jordan

Q: Can you tell us what it's about? Can you summarise it for us?

A: It's just about four girls in Leith that are kind of 20-something lassies. They're at that point in their life when they have to start making decisions about things. Not like me about what kind of sort of wigs and eyelashes and costumes and what to wear, but kind of big things about whether they’re gonna settle down, have a family or whether they're gonna stay friends or have a career, whether they're gonna make money, whether all the kind of things, the choices people have to make when they get into their 20s, their late 20s.

Q: Given that everybody knows the brand Irvine Welsh, do you think people will be surprised by Wedding Belles?

A: I don't know. I mean, I hope so. I was surprised, which was the best thing. Every time you do something, you want to surprise and get a reaction from yourself, and it's only then that you get a reaction from anybody else. If it's not moving you, then it's not gonna move anybody else. So, hopefully people will kind of get some kind of reaction from it, yeah.

Q: Did you have a hand in casting the four leads?

A: Well, we talked about it – myself, Dean, Jemma and Phil were talking about what our wish list would be and it was the first four people that came on to... we thought about and it was amazing when we got them all. We couldn't believe it. Because normally, you know, you get one or maybe two, but to get the four of them was just incredible.

Q: So, very exciting?

A: Very, very exciting, yeah. Almost as exciting as my eyebrows here, like:

Q: Have you any plans for the four girls after this feature has finished? Will we see them again, do you think?

A: I mean, we'd love to do some more stuff. Do you know, I've been talking about this? And we think there's much more in the characters, and we've got many ideas for different storylines for them. So I mean we'd love to do a series of Wedding Belles. I mean, whether that's will happen or not, I'm not sure. But we just love the characters so much and we think there's just so much more mileage in them, so... Yeah, I mean, but again, that depends on a lot of things.

Q: Talking of Dean, do you and he have particular roles when you’re writing together or is it more fluid and ad hoc than that? Do you have set tasks?

A: We'll start off and map it out together, then we'll go away and one of us will do a draft and send it to the other. We just keep knocking it back and forward. If we get any blockages, we'll get back together again and start doing it. It’s kind of telepathic, I was gonna say it's like a marriage without the sex, but once he sees me like this I don't know if that will hold for very long, like. But it is. We're just on the same wavelength. You've got a critic as well, which is great thing when writing with somebody. You've got this critic so you save a lot of time, basically.

Q: Cool. Have you known each other long?

A: Quite a while, and when we first met we had a lot... we'd made a lot of mutual friends, who always assumed that we know each other when we didn't. He showed me a script he'd written which I thought was great and, when I had to get somebody to dramatize Filth, I asked him if he wanted to do it. And he did. Unfortunately, the company that was producing it folded so we couldn't do anything with the script but we got used to kind of locking together. We tried doing scripts together and it just took off from there, really, you know?

Q: Fantastic.

A: We've written a lot of crap scripts as well, at the beginning. We served our apprenticeship with them really. So we've got into a mode now of doing it.
