Misfits has been nominated for 'Best Drama Series' - congratulations! How do you feel?
"It's amazing. I think we're completely overwhelmed by it. It's so flattering, and I think we're so proud of the show. It's just so nice that the industry and the general public has recognised it as something that's a bit of fun."
The show keeps getting better and better.
"Credit to [executive producer] Howard Overman's amazing writing - he's just a bit of a genius, really!"
Robert Sheehan and Lauren Socha have both been nominated as individuals - do you think they can win?
"I think they can do it. I think they're both obviously fantastic, really, really strong actors. It's Lauren's second time being nominated which is amazing. I really think they can. I think they've got stiff competition as always with the BAFTAs but I think they definitely earned their place there."
There was a massive twist at the end of the Christmas special - do you know anything about the new powers yet?
"We do know about new powers. I can't tell you anything, unfortunately! But yeah, I think it will be pretty exciting."
Will it change a lot of stuff?
"I think so, yeah!"
What about Robert Sheehan leaving the show - is it weird for you?
"It'll be weird. It'll be a bit sad, it'll be sad to lose him. We all got on so well. But I think, as I say, credit to Howard Overman's writing, he's a clever man and I think he'll find ways to fill the void and find new characters to take his place."
You've got Rudy coming, played by Joe Gilgun.
"[Joe's] a very fantastic actor, which is really exciting."
So can Misfits win 'Best Drama' for the second year in a row?
"I hope so! I mean, we've got really stiff competition - Downton Abbey and, you know, Sherlock. It's really stiff. But I think... I don't know, fingers crossed. It's just really nice to be nominated and to be invited along, to be honest!"
Congratulations on Misfits being BAFTA-nominated again! Do you think it can win 'Best Drama Series' two years in a row?
"I don't know! I don't know, there's some pretty good, stiff competition, as there was last year. It's just nice to get nominated and try and enjoy the ceremony."
The show's up against Downton Abbey, Being Human and Sherlock - what do you think is its biggest competition?
"It's very difficult. I think Sherlock's got a really good chance. And Downton Abbey as well was really successful and it's that kind of show... I don't know!"
Robert and Lauren are both nominated as well - how do you rate their chances?
"I think they've got good shots, so I hope they win."
Have you got any plans for the ceremony? Do you think you'll be nervous?
"It's always a bit nervewracking, even if you try and tell yourself, 'Nah, I'm not going to be nervous, it doesn't matter anyway'. But you always get caught up in the occasion. I think it's going to be fun."
You're filming the third series of Misfits at the moment - is it strange without Robert?
"It is strange, yeah. It's quite weird. But Joe Gilgun's come in and he's doing a great job. He's really funny and he's different, but in a good way, and it's in a way that the show is moving forward. It's a shame about Robert, but what can you do?"
So you're having fun working with Joe?
"Yeah, it's great. He's got so much energy. He's different to Robert, but he's got this brilliant energy - he's got a hell of an engine on him!"
Joe's playing Rudy - is he a similar character to Nathan, or is it a different group dynamic?
"It is in a way. The analogy I always think of is that he's less like the frontman, more like the crazy drummer - Keith Moon or something like that!"
There's going to be an online film where we say goodbye to Nathan and hello to Rudy - can you tell us anything about that?
"Um. No! I'm afraid not!"
It was worth a shot! Simon's probably one of the characters who's developed the most over the series - will we see him continue to change in the new episodes?
"I think so, yeah. Obviously he needs to finish that journey to becoming the Superhoodie character. I haven't actually seen all the scripts yet but you do see him become a lot more confident and having this ambition to become this superhero character."
You've been able to play both the future Simon and the present Simon - was that fun?
"Yeah, it was amazing. It was a great challenge. And also to kind of try and make the present Simon become the future Simon, if you know what I mean - have all those little beats where you can show a little flicker of it... The difficulty was - because the statuses were going from one to, like, ten - to then also keep that sense of Simon in that really confident character. That was quite a challenge."
Will we see Alisha and Simon's romance begin to develop?
"Yeah, I think a lot of that. It's going to become quite prominent. They're sort of together now in this new series."
In the last series, the group finished their community service, but Lauren recently posted a photo on Twitter of you wearing your orange jumpsuits again - which I'm very happy about because it wouldn't be the same without them.
"No, it wouldn't!"
So can you give us any hints about how the guys end up doing community service again?
"In a classic Misfits way where they just do something stupid! That's all I can say."
There was a big twist at the end of the Christmas special with the group swapping their powers - do they definitely have new abilities now?
"Yeah, everybody's got a new power."
Can you tell us anything at all? How about... are they useful powers?
"Well, I think they probably set out thinking that they would be, but... they're still rubbish!"
What sort of things will the group face this year? We've seen odd powers and odd villains in the past - can you tease anything about what we can expect this series?
"I think just more and even madder. There's loads of powers and the powers start coming out even more again this series. There's some quite crazy storylines as well. From what I've read, there's some really great ideas that Howard's come up with and the team's come up with. He's got an incredible brain. Mental, but incredible!"
So, what would you say to get fans excited about the new series?
"I just think it's bigger and better. The scripts are great and I think the ideas are there and it's just more Misfits!"
Do you think the show could be up for a BAFTA again next year?
"I don't know! Yeah, hopefully. Obviously you never know, and I've only seen the first three scripts. There's loads of others to come out. The standard's been so high the last two years, so I can't see why it won't be again. It's exciting."
If Misfits does win on Sunday, how will you celebrate?
"Um... Get really p*ssed!"
The Philips British Academy Television Awards will be held in London on Sunday. The ceremony will be broadcast from 8pm on BBC One.
