Robert Pattinson says 'Twilight' is like a "virus".
The actor - who plays vampire Edward Cullen in the movie franchise - is amazed at the response he's had from fans around the world to the latest instalment, 'New Moon'.
He said: "We went to Japan earlier on in the year. There wasn't that much of a reaction - but last week when we went again, it suddenly exploded, the same as in England.
"I don't know how, it just explodes so quickly. It takes seven months to take hold - it's like a virus."
