Season two of the brilliant Glee is about to hit the shelves on DVD box-set so we grabbed Dianna Agron and Kevin McHale, who play Quinn and Artie, for a quick chat!

Season two includes a feature on filming in New York. What are your memories of the shoot?

Dianna: It was something we’d never experienced before. People were excited because we’d never filmed there and there are no regulations on where you can and can’t stand so, to be in Central Park and fans were running with us, the crew had to hold people back and there was a paparazzi line… We kept turning around wondering who everyone was making a fuss about and realising it was us. Everybody made such a fuss about us being there and it’s very nice to have that enthusiasm surrounding us, although it often made our assistant directors a bit nervous because they couldn’t get people out of the shots and we were always up against the clock. We had half an hour at one location, an hour at another. It was hilarious. It was like a circus.

Do you have a favourite song from this season?

Dianna: For me it’s The Time Warp simply because of the fun costumes we got to wear.

Kevin: Proud Mary was funny. Having everybody in wheelchairs and people falling over was kind of hilarious. Actually everyone was pretty good, although there were a few times I had to teach them how to balance their weight.

Dianna: Everybody had at least one fall, minus Kevin.

Were you disappointed the Glee club didn’t win nationals at the end of the season?

Kevin: I was disappointed. I guess we all assumed we’d win nationals – that was the view among us, we’d lost the first year so we’d win the second year. And then when we heard we weren’t winning it was like: “Maybe they’re just messing with us so it doesn’t get leaked.”

Dianna: TV isn’t like film where you get a script and that’s the map, that’s what you’re sticking by, and even if things change it’s minimal. TV is always flying by the seat of your pants.

Do you worry about having to leave the show when your characters get older?

Kevin: As much as the show is exaggerated in a lot of aspects it’s also very realistic and us graduating is just part of what happens in high school. We don’t want to be 40 and still trying to play high school students. They’ve already started bringing new characters into the show and integrating new people, and that’s the natural process of what really happens in school.

Do camera flashes at the live shows put you off?

Kevin: Not at all. Flashes are just going off everywhere and it’s like there are 16,000 cameras being used at the same time. It’s insane but also beautiful.

Dianna: Somebody had an iPad out the other night, filming us.

Kevin: Everyone puts their cameras up so they can document the show but they’re not even watching, they’re just watching their cameras.

Dianna: I think that’s a new thing with Twitter and Facebook and stuff like that. You want to be able to share with your friends where you’ve been and what you’ve done, but perhaps you need to find a balance. If you’re watching it through your camera screen you might as well be at home watching it on YouTube, but then you still feel the vibrations of it and the energy of the crowd when you’re at the show.

Kevin, you were in Katy Perry’s Last Friday Night music video, what was that like?

Kevin: That was fun. We do, like, five music videos on each episode of Glee so to not actually be the person singing and getting to play dress-up was cool. I grew up being obsessed with music videos. I would turn on MTV Hits in every room in my house and watch it all day, which was kind of pathetic. But to be part of a cool video like Katy Perry’s was fun. I got to walk for a change and I almost got to make out with her, but that got edited out.

Why hasn’t she been on the show yet? We think she’d be brilliant!

Kevin: Well, it’s not like she doesn’t have enough to worry about. She’s a tad busy and she told me she’d only had a couple of days off in the past year, but she’s always been super-supportive of the show.

When you’re on tour do you have any pre-show rituals?

Dianna: We have a show circle, then Kevin leads a chant down the hallway. But, before that, you’ll find us sleeping in any corner or couch available.
