So, if Stargate's Dr. Jennifer Keller and Firefly's Kaylee Frye got in a fight, who would win? Actress Jewel Staite doesn't have much doubt about the outcome, as she told Blastr in an exclusive interview in which she discussed her notable sci-fi roles and her new web series, State of Syn.

“Oh poor Jen. She doesn't have a whole lot of fight in her. Plus Kaylee's got one heck of a back up team. I would not want to get on the wrong side of any of those guys on Serenity,” said Staite.

The Canadian actress has become a fan favorite for her impressive roles in Stargate: Atlantis, Wonderfalls, and, of course, Firefly. Staite admits she's grateful for her “great” sci-fi roles as she discussed what she loved about each part:

Dr. Jennifer Keller, Stargate: Atlantis:

“Keller was a super brain, sort of a Doogie Howser, who got thrust into the role of the Chief of Medicine on Atlantis and way out of her element. I loved her because she was real, and a reluctant hero who was always surprising herself by how capable she really was. Atlantis shot in my hometown of Vancouver, so it was the largest chunk of time I ever got to spend sleeping in my own bed and filming at home. I absolutely adored my time on that show,” said Staite.

Heidi Gotts, Wonderfalls:

“Wonderfalls was a total riot to do. Heidi was such a nutbar, and I got to run around in these ridiculous Jersey Shore tracksuits and high heels wreaking havoc on poor Jaye. Any time you get to play an extreme character like that and are given carte blanche to just run with it, it's such an incredible amount of fun. I would die to work with [creator] Bryan Fuller again, and [star] Caroline [Dhavernas] was such a doll,” she said.

Kaylee Frye, Firefly and Serenity:

“Oh, Firefly. The show that changed my life. I can't say enough about the positivity that show has brought me. Besides it being pretty much the best experience of my career, in terms of the incredible people I met that I'm still lucky enough to call some of my best friends, it introduced me to the world of science fiction conventions. I'm still invited all over the world to these things where I basically sit and sign autographs and get showered with compliments. I cannot tell you enough how much fun they are. So, because of Firefly, I've also gotten to travel around the world. How amazing is that? I'll never get sick of talking about it, I'm so proud of it even now, and I'm blessed to be a part of it and its fandom. Firefly fans are the best fans in the world, and I'll be a Browncoat forever,” said Staite.

And yes, if the right part came along, she'd do another sci-fi role:

“The thing I love about science fiction now is that it's become 'cool' to love it. It's so much more mainstream than it used to be, and it's become cool to be a nerd. My mom always told me the geeks shall inherit the earth, and they should – geeks are the brains of the operation! I love the stories that are being told nowadays in sci-fi, and I feel like it's just getting revved up. I've put the bug out there that I'd love to do something sci-fi related again full-time, so I'm just reading scripts and waiting for the right thing to come along. Sci-fi fans are the most devoted fans out there, and it's because of them I've had such a great and lucky career,” she said.
