How much do you know about the next season and how much are you told? How much do you want to know, even?
"We always want to know everything! But from what they tell us now to what we're going to end up doing in three months' time, a lot changes. So I have an idea of what's happening next season but whatever idea I have will be quite a bit different. They haven't started writing scripts yet. The writers get a week off and then they're right back at it. I think one of the things that is good is that it's slowing down a little bit and when you watch an episode – at the end of the episode, as you said before, you know what you've just watched. You know what happened and you know who it was about, as opposed to a frenzy of story and effects and things blowing up. It's much more focused."
Greg caused a bit of chaos on the internet, on his Twitter, a couple of weeks ago suggesting that the show might not be back...
"He didn't suggest that, he said 'We're saying goodbye at the end of the season and we don't know who's back – we don't know who of us is back'. He was referring mostly to crew. The actors are one of 200 people on the set and these are people we work with every day. I mean I'll work with James from Props and Wendy from Makeup more than I'm going to work with any of the other actors! So when he said 'we're saying goodbye to everybody' I really think that's what he meant and when I read the comment – what he literally said – I think it was much more about the crew. Some crew members take other jobs, some come back, some don't and I think that's really more what it was. But it seems like it maybe forced NBC's hand to come out and say 'no no no no!'"
And they've picked you up for 18 episodes next year, haven't they?
"Eighteen to twenty, yeah. But it's also partly because we're going to start early enough that we can finish by Christmas without an interruption. Then they have the Olympics so we would be pre-empted a month centrally anyway, and I think that's why we're talking about a slightly shorter run."
Do you reckon that'll be one volume or two?
"Probably two, but I don't know – I'm just guessing. If it's twenty episodes I'm almost sure it'll be two volumes, but if it's eighteen episodes it might be one – I don't know. It'll depend on when they sit down to figure out exactly what stories and what amount of time they want to tell in the first say, ten episodes. But if it's twenty episodes it'll probably be two volumes."
