The cast reports they were surprised by the size of the London premiere:
Hundreds of screaming teenage girls braved the cold for the UK premiere of vampire love story Twilight, in London’s Leicester Square.
Stars Robert Pattinson, 22, and Kristen Stewart, 18, walked down a black carpet blasted with dry ice.
Briton Pattinson said of his fans: “It’s absolutely mad – they’re here for the character, not for me.”
The film, based on the series of novels by Stephanie Meyer, opens in UK cinemas on 19 December.
In its first weekend in US cinemas, Twilight outsold new James Bond film Quantum of Solace and High School Musical 3 taking $70.6m (£46m).
It also set a new record for the biggest opening weekend for a female-directed film.
Director Catherine Hardwicke said casting Pattinson for the role of Edward had been an easy decision.
“Robert and Kristen have this amazing sexual chemistry between them – we could see it in the audition. That’s why we cast them, you can’t create that. It has to be there,” she said.
The film has turned Pattinson, who previously starred in Harry Potter and the Goblet of Fire, into an international sex symbol.
“I just turn up at places and people scream, it just feels like my job,” he said.
Stewart said members of the cast were surprised by the scale of the London premiere.
“It is much bigger than the one that we had in LA,” she said.
“It’s cool because our studio was like, ‘don’t expect anything, it’s not going to be so big over there’.
“Apparently we were all very wrong.”
Twilight tells the story of Bella Swan who is swept up in a supernatural romance with smouldering Edward Cullen.
He is part of a family of eternally young vampires fighting their nature by refusing to feed off humans.
Meyer’s series of books have sold 18 million copies in the US.
