ORLAND PARK, Ill. — “Bite me.”

It’s a request British actor Robert Pattinson gets almost daily as star of the new vampire film “Twilight” (opening Nov. 21).

“It’s crazy,” said Pattinson, 22, waiting inside the Hot Topic store in the Orland Square shopping center. He has to laugh, pretend he hasn’t heard it before.

“Even if you say, ‘No,’ they just wait,” he says. “They just stand there.”

Wednesday night, more than 500 fans waited outside — some since the night before — to ask him the same question or something in that vein. One fan, Orland Park’s Abby Johnson, wore a self-made T-shirt that read: “Edward Cullen Make Me Immortal” (Edward is Pattinson’s fanged alter ego.) As the clock reached 6 p.m., the time he’d start signing autographs, the crowd started screaming, counting down, “Three … two … one …” Chaos.

“Oh my God,” said Pattinson, laughing nervously at the uproar. “Are they going to blow (the place) up?”

Mostly, they just filed in peacefully, gushing and smiling — though for the public Q&A session later, the crowd seemed to have swelled to a frenzied mass.

In what follows, Pattinson talks about his new movie, immortality and Doctor Who.

Q. What does Edward, a 108year-old vampire, see in a 17-year-old girl?

A. He’s lived for 108 years, but he still has the same brain as a 17-year-old. He experiences the world as a 17-year-old. He’s kind of mature in some ways.

But if you were in the body of a 17-year-old, I don’t think you’d go for a 108-year-old woman.

Q. But why high school? For you personally, wouldn’t 80 years of high school be hell?

A. Definitely. I would hate it.

That was one of the most difficult things to figure out. You think he’d stay in college, or be a street kid. It’d be way cooler. But I think the whole concept of it is: He’s like an addict. I think he wants to make his life really, really, really boring.

Q. This question is from Jennifer Armour, a fan waiting in line. David Tennant, the current star of “Doctor Who,” is quitting in 2010. Would you consider taking up the mantle?

A. The Doctor is great. … Yeah, maybe. I did grow up watching it. I loved it when I was a kid. In fact, I met one of them the other day, Sylvester McCoy (the seventh Doctor). He’s one of the few people I’ve asked for an autograph.
