While in New York promoting his Calvin Klein ads at Macy’s, Kellan had a quick chat with Metro US.

Any surprises in store for the next “Twilight” movie, “Eclipse”?
It’s really tough for our characters — the movies are based on the books. So a lot of characters are like — they barely have lines, they’re barely in it. But you can’t rewrite the books. I’m just grateful to have a line or a purpose in there. But definitely, Emmett’s character and story grow immensely in “Eclipse.” You see the battle between the [vampire] newborns and you see the werewolves coming along. It’s a big fighting movie and that’s Emmett’s strength. So there’s the fighting and the big brother role, which is nice.

Have you seen the line of fans waiting outside for you?
No, I didn’t actually. But I love the fans. We in the “Twilight” franchise have the best fans. And it’s really cool to see them come out to something other than “Twilight,” you know? ’Cause then it feels more personal. Then they’re Kellan’s fans.

Before you began acting, you were a model. What about Calvin Klein underwear made you want to go back to modeling again?
I got into modeling because I was in a financial crisis. It was a great way to make money. I never thought I was pretty by any means. But it was great to be a part of that world. And the pinnacle of that world is to be on a billboard. I grew up wearing Calvin Klein. As a model, I dreamt of being Marky Mark, being on a billboard, and selling that company.

Speaking of Marky Mark, were you nervous about comparisons when shooting this campaign?
I was thrilled. I loved Marky-Mark’s campaign. And by no means was I trying to fill his britches or, uh, boxer-briefs. I was just stepping into them and doing my best to follow his footsteps. And that’s all I can hope and pray for. I think the audience has really enjoyed the campaign, so it’s nice to be a part of it.

Since you were already in production, did you really have to prepare physically for this Calvin Klein campaign?
Well, I did. You know Emmett, my character, is more of the big guy. So I don’t need the washboard abs, just the size. I did a lot of push-ups and tons of protein. But for Calvin Klein, it’s underwear. So I called up my buddy Rich McDonald, who’s a personal trainer friend of mine. He put me on a great diet that took out the candy (which I love) and the carbs past 4 o’clock (which I break here and there). And he told me a great thing, which is to drink water as much as you can. ’Cause when you don’t drink water, your body needs to hold on to it to stay hydrated. So I started training with him and he got me into the shape that I need to be for the campaign. I trained for two weeks.
