DETAILS: When you were cast in Game of Thrones, you had to sign a nudity clause agreeing to show your stuff. But you're always buried in chain mail and fur. What's it like to be off in the frozen tundra while the rest of your cast is cavorting naked?
Kit Harington: I actually always loved that about the part—I get my own crazy story line completely separate from everyone else's. My bits are predominantly filmed in Belfast and Iceland. I tend to be surrounded by bearded men. We get soaking wet in the rain and snow and it weighs down the heavy leathers even more. Meanwhile, everyone else is coming back from Morocco, going, "Oh, I just had a scene in a sauna somewhere."

DETAILS: You auditioned after playing the lead in the original West End production of War Horse. Did you have your signature Mane back then?
Kit Harington: No. I had to wear a wig for the pilot, and I hated it. So I grew out my hair and it became this big curly mop. As an actor, you don't have much choice about your appearance. It's a good excuse for looking ridiculous.

DETAILS: What made you take up acting in the first place?
Kit Harington: When I was 14, I saw Waiting for Godot. It's one of those plays that if it's done badly is absolutely dire and can put you off acting for life. But I was laughing all the way through it. I remember thinking, "That's what I want to do."

DETAILS: Any welcome-to-Hollywood moments since Game of Thrones took off?
Kit Harington: I get stopped on the street a lot. Within the show, there were certain iconic characters, and I managed to bag one of them. I want to play other parts, but at the moment I have to accept that Jon Snow is who I am. I fully expect to be thought of as Jon Snow for a little while—or forever.

DETAILS: But you are appearing in the fantasy epic Seventh Son later this year alongside Jeff Bridges. What was it like filming with the dude?
Kit Harington: Jeff Bridges is one of those icons that I put on a very high pedestal, so just to get to chill with him off-camera on cold, rainy days was surreal.

DETAILS: Here's something else that's surreal. There's a Game of Thrones beer. Did you know this stuff exists?
Kit Harington: No, but that's brilliant! I love that about the show—the real hard-core fans want to drink the beer from that world and dress up in the same costumes. I think it's wonderful that people invest so much in the world that we've created. Why haven't they sent me any?
