PORTLAND, Oregon — When it comes to “Twilight” Tuesday here at MTV, we try to operate on one simple motto: Ask, and ye shall receive.

In virtually every article we’ve written covering the upcoming “Twilight” movie, there’s one comment we can count on receiving: “Give us more Kellan Lutz!” And although the 23-year-old actor isn’t a household name, a quick search of sites like Kellmett Happens and the Twilight Lexicon Forum show the type of love that has had Twilighters sending gift baskets to Lutz ever since he landed the role of burly teddy bear Emmett Cullen. (Lutz expresses his genuine appreciation of enthusiastic “Twilight” fans in the MTV Movies blog.)

As you’ll see from this on-set interview with MTV, Lutz (who’s also on the new “90210″ this fall) is an endearingly normal guy who nevertheless takes his acting — and Stephenie Meyer’s vampire series — very seriously. As he reveals a love for “Bill & Ted,” the missing “Twilight” moment he’s eager to shoot and the circumstances that nearly made him miss the gig, something tells us the Twilighters will suck this up like fresh blood.

MTV: Give us your take on Emmett.

Kellan Lutz: All right, Emmett is the coolest guy of them all, that’s pretty much it. [Laughs.] No, he’s the protector; he’s like the doorman for the family. He’s really just there to protect and lighten everything up that Rosalie throws at the family. She’s the emotional letdown; she really brings everyone down. Carlisle will be like, “Emmett, take care of her.” He’s really just the protector, the goofball. He’s there to make them laugh, and he’s there to have a good time.
