Can you give us a few hints on what's coming up in the second season of Warehouse 13?
"I can tell you that we're going to have a new super-villain. I think that people who liked the show last year will really love it this year. I think this season the writers weeded out what didn't work last year and have really found what it is that people like about the show. It's a family show at its core. Even though it's about these warehouse people looking for artifacts, the artifacts are really just a plot device to get to the core of the show. It's really a show about relationships. I think people will really enjoy the relationships as they grow and develop this year. Also, the people at Syfy have given us more money this year, so the show feels more expansive and the universe itself feels bigger. And they've allowed the writers to write comedy this year. Whereas last year, the comedy was more improvised stuff on the set, this time it's scripted. I think the show generally is better."
There's a crossover with Eureka too. What can you tell us about that?
"Fargo (Neil Grayston) from Eureka comes to the warehouse to install a new operating system for the warehouse computer because it's antiquated, and because he's Fargo, he kind of screws things up! We have René Auberjonois as our guest star in that episode and he's awesome."
Tell us a bit about the guest stars appearing in this season.
"Tia Carrere comes on to play an old flame of Pete's. She's one of the most awesome people I've ever met. She's just a fantastic lady and a great actress. We also have Lindsay Wagner, plus Jewel Staite and Sean Maher from Firefly. Judd Hirsch plays Artie's dad and Armin Shimmerman from Star Trek comes on too. That's one thing that Syfy does so well - they know the value of a good guest star, in regards to their fanbase. They've done a great job of implanting these wonderful actors into our show."
On Twitter, you mentioned that you wanted Bruce Campbell to appear on the show. Are there any other actors you'd like to appear?
"Bruce Campbell would be my first one. I'd like to see Nathan Fillion come and do an episode of the show. Nathan and I are old buddies so that would be cool. It'd be nice to get Ryan Reynolds to come and do an episode, but he's probably a little bit busy these days with his enormous film career. I'd love to see Tony Shalhoub do an episode. Neil Patrick Harris as well. These are all old buddies of mine who I've worked with and I admire their work. Plus, they owe me money!"
How do you feel now that Warehouse 13 is such a big success?
"It's been a wonderful event, it's been great for me. It's nice to finally land on a show that gives me a little bit of recognition for who I am, in regards to my career. Before this, everybody thought I was David Boreanaz! I signed a few autographs and got a few free pizzas pretending to be David Boreanaz. Now I can live my life as Eddie McClintock and people recognise me for that. I get my own pizzas!"
What do you think is the appeal of the show?
"I think the show at its core is about relationships and the team that occupy the warehouse. That's what great about it. I was just at DragonCon this weekend, and half of the people who were coming up to the table to meet me were young kids, with their parents. It's really a family show - about a family and for families. That's the best type of show, in my opinion. It doesn't exclude anyone. It's very inclusive and you don't have to send the kids into the other room. It doesn't talk down to the kids and it doesn't pander to the lowest common denominator either. It's smart and informative, and I think that's what has caused it to be so successful."
Your co-star Joanne Kelly has previously said that she's against Pete and Myka getting together. Do you think a romance could work?
"I think a romance could work between the two of them, but I like the fact that they have enough respect for their jobs and for each other to not cross that line. I think it makes us more honourable characters. I think it makes them more interesting to watch, because they respect the co-worker dynamic. Getting together with the people that you work with is generally not a good idea. I think it's more interesting to keep them seperate for now. Maybe in season ten or eleven, they can bump their wheelchairs into one another in some kind of odd mating ritual!"
Were you keen to avoid the 'will they/won't they' cliché on the show?
"Yeah. I remember when the series started, everybody said 'Oh no, it's the two angst-ridden leads that are desperately in love with each other but they're not allowed to be together because it's TV land.' But Pete and Myka are not together because they don't want to be! They actually have a brother/sister relationship and that's OK by them. It would be like kissing your sister. Myka loves Pete, but the thought of seeing him naked makes her shudder. I don't think the thought of seeing Myka naked makes Pete shudder, because she's hot!"
There's going to be a Christmas special this year. Can you tell us anything about that?
"Paul Blackthorne guest stars and he has a little run-in with Santa. He is just so amazing. He's almost like Sean Connery - there's a lot of gravitas with him. He really put it all on the line when he was working with us, and I respect that. He did a great job and I think it's going to be a really fun episode."
What are the chances of a third season?
"I think it's unofficial. Obviously Syfy hasn't announced it. This is just speculation, but we're getting ready to run up against some of the fall premieres. Our show last year got swallowed up a little bit by the fall premieres of the network shows, so I think Syfy is waiting for the best moment to speak of the renewal, in the hope that more people will stick around this season."
The second season of Warehouse 13 begins Thursday at 9pm on Syfy.
