We love Sharon Horgan at Frost. Funny and endlessly talented, we can’t wait to catch her new show, Catastrophe. Find out more in the interview below.

Explain a bit about Catastrophe. What’s the concept of the series?

It’s an unromantic look at a romance, I think. It’s about a couple who meet on a one night stand, and end up spending this great week together, and that should be it. But she gets pregnant, and he decides to do what he thinks is the right thing and stuck around. And she’s happy for him to lend a hand, as she can’t really be on her own. So they have this speed-life version of a relationship, where everything starts going to shit from the moment they get together. But the way it differs from a normal relationship is that they don’t really know each other, they’re just getting to know each other while all this shit’s happening. Going to have a pregnancy scan and getting bad news is hardcore enough with someone you’ve been with for years. But having to do it with someone who’s almost a stranger to you… And as the series progresses, more and more catastrophic things happen to them. And they’re slowly falling in love while all this shit’s going down.

Where did the idea come from? Why did you want to write this?

I guess because of my situation, and Rob’s situation, and the fact that you kind of want to write about what you know. I knew what sort of material he did with his stand up, he knew the kind if stuff I did, and we just figured this subject matter would suit our styles the best. And we both had a series of shitty things happen to us in our relationships or in our experiences as child rearers, and we felt like it would be nice to bring people a warts-and-all picture of a relationship. Still romantic, still a love story, but a real version of it.

Am I right in thinking that you and Rob met over Twitter?

Yeah, that’s right. I started following him because Graham Linehan had retweeted him a few times, and I found him extremely funny. And totally filthy. And then I noticed he was following me, and then he got in touch on a private message saying he liked what I did. I thought that was sweet, and when I was over in the States we decided to meet up – it’s always interesting,meeting people who kind of do what you do but in a different medium.And then we just kept meeting up, over the years, and eventually found the right thing to collaborate on. But that was kind of scary when we started writing – you never know whether these things are going to be a disaster or not. It can be really hard to write with someone, it’s very intimate and exposing. But the relationship worked immediately, it felt fun and easy.

How did that process work? Presumably you were separated by the Atlantic?

Yeah. For the Pilot, we talked a lot across the Atlantic, and then I was in America working again, and we grabbed what time we could. And then, for the second episode, Rob was over here for a while, and then we went back and forth over Skype. When Channel 4 said they wanted to do the full series, we wrote all the first drafts on Skype. We Skyped each other the whole time. But then we kind of realised that you need to be in a room, reading the script aloud, making changes as we’d go. So we did a lot of rewriting when I was over in LA. But now he’s moved here, he lives here now, which makes it much easier.

Did you find that you each tended to write more for your own characters?

I don’t think it did pan out like that. Maybe a little bit initially. What we did end up doing was rubbing our corners off a bit. If I’d write something that sounded a bit harsh, for either character, he’d give it a bit of California sweetness. And if he wrote something that I thought sounded too warm and American, I’d write a bit of Irish acerbic into it.

Judging from the trailer, your character isn’t going to have the most pleasant pregnancy. Is that partly based on your experiences? What were your pregnancies like?

I would say pretty tricky. But it wasn’t just mine that we based it on. We used mine and Rob’s wife’s experiences, we mixed it all in. Any shit that happened to me we multiplied by two, because we had another pregnancy to steal from as well. But you ask any woman who’s been through it. There won’t be too many rosy stories in there. I got knocked over by my dog and broke my knee. My pelvis parted, so I was on crutches for most of it. My second one, my ribs felt like they were splitting because My baby was so massive. A lot went wrong – the same with Rob’s wife – which is why we were able to throw that all in there. I know there are women out there who loved being pregnant, but that wasn’t my experience.

While you were filming, did you have to wear a bump that grew steadily bigger throughout the series?

Yes. I had three or four bumps over the series. It was good, because it genuinely felt incredibly uncomfortable, especially the really big one. It was really heavy, and it did make me relive it, because my back was fucked at the end of it, and I remember feeling exactly the same at the end of the pregnancy. But it worked – whenever I needed to be grumpy and fed up in character, I generally was.

The show’s got a great cast, including Ashley Jensen and the great Carrie Fisher. That must have felt so exciting, getting them on board.

Yeah, it was. It kind of felt like that for everyone who came on board. Every time we got the person we really wanted, we were pinching ourselves. Everyone in the cast is phenomenal, top of their game. But we did end up feeling “Shit, why weren’t they in it more?” with every supporting character. They’re all actors you want to see more of.

Carrie Fisher’s a legend, isn’t she? We were madly excited when she came down on set. We were all acting like dicks. We were running around like grinning weirdoes. I was going over her lines with her, lying on a bed by her side because she was a bit jet-lagged, and I felt like “Yeah, this is it. I’ve reached the heights now.” And Ashley is just incredibly funny, and great to be around. She’s a lovely,. Funny, warm presence all the time. Mark Bonnar, you can’t take your eyes off him. I can’t wait for people to see it, just for the supporting cast.

In the past, you’ve done a couple of factual programmes for Channel 4. Is that something that you’d like to do more of in the future?

No. I really loved that they asked me to do it, and allowed me to make documentaries on whatever I wanted. I hooked up with my friend, Chloe Thomas, and we went out and talked about the stuff that we were interested in, and our own experience. And at the time, that was motherhood, and mid-life crises, and marriage, so those were the three films we made. But it’s not really something I want to pursue any further than that for now. I said what I had to say. And it’s hard work! It’s tough, because you’ve got no script, and a lot of it is built in the edit, and a lot of it is down to chance. These are real people that you’re dealing with, you have to tread carefully. I had a great experience, and I’m glad I got to do them, but I think I’d rather just watch that sort of thing from now on.

In your body of work, what are you most proud of? And where does Catastrophe sit within that?

I’m still very proud of Pulling. It was the first sitcom I ever made, and it was a situation where someone took a leap of faith, and let us have a go. So we ended up making something that we really liked, and had enormous fun doing, with the people that we wanted to do it with. And Catastrophe, for me, feels very similar. I felt with Pulling that I couldn’t have made it at any other time, and I think with Catastrophe, I couldn’t have made it even three or four years ago. It feels like the perfect thing for this moment, for the stories that I have to tell. It’s the same thing, just being given proper creative scope by Channel 4 to make the show that we wanted to make. I guess we’ll have to wait and see now what people think, but it was an enormous pleasure. I felt as emotional at the end of filming as I did at the end of Pulling, just the feeling that I’d really, really enjoyed it and I was very lucky.

Catastrophe starts on Monday 19th January at 10pm on Channel 4
