The British star has been catapulted to stardom thanks to his role as Edward Cullen in the movie, and fans worldwide are going crazy for the actor.

But Pattinson admits he doesn't understand the craziness of the story, despite reading the "addictive" books.

He tells British morning show GMTV, "The extent to which I've seen the insanity around this story, I don't get it.

"I read the book and the whole series and I can understand they're very addictive but seeing the extent to which some people are just obsessed. I mean people yesterday at the premiere, some were like 'I've come from Brazil just to stand here for the premiere'."

The Harry Potter actor is impressed with the lengths fans go to to support the film - but he can't comprehend what they want from him.

He often tries to placate them by jokingly offering himself to them: "Literally, I'm like 'Do you wanna (sic) come home with me?' Please don't answer that! I'm just saying it to be nice!"

And Pattinson finds it hard to live up to the hype surrounding the vampire franchise.

He adds, "I didn't know anything about the hype when I was making it so now I just turn up and literally I used to get so stressed out because people are screaming at you. And you just think 'What do I have to do? I cant give anything back to you at all.'"
