Robert Pattinson, 24, once said in an interview that he worried that so many good things have happened to him at such an early age.
"I guess I just thought if too many good things happen, then you're going to die at 30," he explains in a new Nightline interview airing Monday. "I didn't want that to happen. "Yeah, so probably, I'm going to die at 30. Actually, it's God saying, 'Hey, you shouldn't have asked for too much.'"
Pattinson says going from a little-known British actor to an A-list heartthrob has been "crazy."
"It's not what people tell you when people warn you of being an actor," he says. "If and when I have children, [and] they ask if they want to be actors, I'm like 'Yeah, it's great. You don't have to do anything. Everything goes right.'"
For the most part, Pattinson says he is enjoying fame "rather than looking like it's freaking you out and you want to leave."
The one downfall?
"I used to spend a lot of time walking in cities by myself, and I can't really do that without being, um, a little paranoid," he says. "You get better at hiding and you get better at choosing which areas are the right areas to go to. And you also get better at interacting with strangers."
Having his costars around helps, he says.
The Twilight franchise -- the film's third installment, Eclipse, opens June 30 -- has become "something much bigger than we ever thought it would be ... that everyone sort of sticks together and supports each other ... everyone's so young still and no one's really going around stabbing each other in the back yet."
Laughing, he adds, "There are still two more movies."
