Digital Spy has an interview with Robert Sheehan aka Nathan in Misfits. He goes into more detail about why he decided to leave the show; Nathan’s online exit and replacement; and a possible guest appearance in future.

I’ve got to ask – why did you decide to leave Misfits?
“[I decided] well before we finished series two. There’s a strange kind of a theme of… There’s a few articles I’ve seen on the internet or whatever about how I’ve left Misfits to go off and do films and that’s all so bulls**t, that’s complete nonsense. I left Misfits to go off and do other stuff, completely unspecific. I just left because a rolling stone gathers no moss, as they say, and I just wanted to p*ss off and do other things, you know? It’s nice that the show’s successful but it doesn’t mean complete blind and unadmonished loyalty – ‘If something is very successful you should stick to it like a barnacle!’ That’s definitely not my thinking.”So it’s just that you wanted to try new things?
“Yeah. If something’s good I’ll do it down the back of a pub, you know? It doesn’t matter if it’s on a big cinema screen.”

Were you surprised by the outcry from fans when you announced you were leaving?
“Well, they’re very internet active, fans of Misfits. Their outcry was probably displayed across the web very dramatically but I think it’s only because they’re very, very internet friendly. They tweet and Facebook all day long. But yeah, I was flattered by the outrage and the shock. It means they’ll miss me! But I’m sure as soon as episode one of series three starts they’ll have forgotten all about me because old Joseph Gilgun, who’s brilliant and funny and hilarious, is coming in and he’s doing a part. He’s the fifth member of the gang now.”

Do you think he’ll be a good addition to the show?
“Yeah, he’s brilliant. He’s absolutely brilliant, that guy. So they’ve cast well. They’re lucky to have got him, I think.”

Now that filming on the new series of Misfits has started, do you have any regrets, or do you definitely think you made the right decision?
“I think I’ve made the right decision, yeah… I think they started filming last Monday but I’ve not been involved so I’ve not been anywhere near the production. I was involved in one online film but that was just me so I didn’t come across any of the others in the midst of filming.”

It’s just you in the online film?
“Yeah, it just involves me and also Joseph’s character a little bit.”

Can you tell us anything about it?
“No, because they’d probably cut my head off!”

You’re not working on Misfits anymore, you can do what you want.
“[laughs] Yeah! Bad blood, bad blood! But yeah, it’s a film to give me a fond and comedic farewell, I suppose. And not make the show too much about me leaving, at the same time.”

Obviously we don’t know what happens to Nathan in the film, but if it was possible would you ever return to Misfits for a guest appearance?
“Ah, you never know. There’s no point in saying never. It holds a very fond little place in my heart. No, it’s been a great big part of my life and there’s no point in turning your back on something completely. I’m not doing that, I would never say never. But I suppose it depends how many series of the show there’s going to be. I suppose there’s room for many more.”
