The show won a BAFTA in 2016. Who has custody of it?

S: We got one each! It was the most exciting bit of the night, realising that we got one each.

R: Some awards we’ve had to divvy up. But BAFTA make one for each named recipient, so thanks BAFTA!

What is it like working with the children on the show? Do you have to get to know them really well so they don’t recoil when you pick them up?

S: They like us!

R: Yeah they like us, and we like them. They’re lovely. Babies are an absolute pleasure. Sonny and Dexter, who are the twins who play Frankie, are a bit older. They’re wonderful, but they’re a little harder to work with, because it’s a super-unnatural situation to be in. Working on set is very artificial and bizarre, and for kids it’s like “Why would we do it again? That’s crazy!” And then you have to be like “Yes, it is crazy, but not only are we going to do it one more time, we’re going to do it 22 more times. “And they’re like “That’s INSANE!” So they’re having a tough time with it, but that’s only because they’re healthy, wonderful children.

S: But we both like the company of kids, we like hanging out with kids, so it makes it easier. When the cameras stop rolling, you can have a laugh with them. But you can’t get them too geed up, because then they’re all hyper. You find yourself going “Shit, why did I tickle him?” You have to know how to play it. But when they bring in a baby or one of the twins, we really enjoy it.

R: On a set filled with smelly adults it’s pretty nice to have a kid come in now and again.

You briefly reference Trump and Brexit in ep 1 of the new series. Will there be any more nods to the way the world is going?

R: Not too much.

S: A tiny bit more Brexit stuff.

R: We’re not trying to make any big comments about that stuff. If you’re alive right now, it’s affecting your life, so we couldn’t not mention it, but as ever, we’re just trying to do it in a way that will create more stress for Rob and Sharon. We’re not trying to fix it!

S: It just came up in that episode because I’m trying to find reasons to get away with behaving the way I did. In the original script it was Brexit and ISIS, and then suddenly that arsehole-buffoon got voted in and we thought “We can’t not mention him!” So we added that in our final read-through.

Rob, you’ve been pretty active of late on Twitter, even by your standards. Is it a relief to be over here and away from the whole shitstorm, or is it frustrating being so distanced and powerless to act?

R: It is weird being over here. And I can’t move back there right now. Not that I want to – we’re happy here, my children go to school here – but it’s weird to not have the option. But he’s got healthcare laws in his sights, and I’m part of a family of five people. And when you have five people, there will be some among them who have what are known as pre-existing conditions, so I can’t responsibly bring my children to a country where healthcare is in such upheaval. So that feels weird. And yeah, I’d like to be outside senators’ offices right now protesting, but I can’t right now. So I’m doing what I can from here.

I read somewhere that you two are planning to do a movie together. Is that a possibility?

S: It’s not in the pipeline. We talk about it A LOT!

R: We talk about it, and then somebody will be like “Hey, get back to set,” or “Where’s that script?”

S: We’d absolutely love to. It’s just a time thing.

Would it be a Catastrophe movie?

S: Not at this point. I think we’d like to try something else. It’d be interesting just to see if something else worked.

When you’re writing, do you guys have more ownership of your own character?

R: No, definitely not. Nothing makes me happier than writing dialogue for the character of Sharon, and have her write it for my character.

S: I think that’s why there’s no stereotypical element to either of them.

When do you start on series 4? Do you need time away from the characters first?

R: It’s a good idea to have a break, to let your mind rest and so you can start to cultivate ideas. So we don’t have a start date, but we’re percolating ideas, I guess.

S: Bit of a break.

Can you ever have a bit of a break, or are you always thinking “Ooh, I might put that into the next series?”

S: You do do that a little bit, yeah.

R: You definitely file things away, I’ve got a ton of stuff in the notes section of my phone. Most of it is fucking insane, though. “Here’s a good idea. What if… Rob walked into a spider’s web!!!”

Catastrophe returns to C4 on February 28.
