Twilight's Final Movie Premieres In London

Thousands of Twilight fans, some of whom had camped out for days, got their reward when the stars of the vampire saga arrived for the premiere of the final film in the series.

Robert Pattinson told frenzied fans in London's Leicester Square that the saga had "changed everything" about his life.

The arrival of the British actor and his co-stars Kristen Stewart and Taylor Lautner was greeted with wild screaming and cheering from thousands of so-called 'Twi-hards'.

Some 6,000 of them packed the square. Many came from outside the UK, with fans from the USA, Dubai, Sweden, Norway and Hungary all amongst the crowd.

Stewart, who plays Bella, dazzled in a black lace jumpsuit, designed by Zuhair Murad.

Meanwhile, her on and off-screen partner Pattinson, who plays Edward, and Lautner, who plays Jacob, wore smart suits.

Pattinson, 26, told the crowds the saga connected to people on a "primal" level.

"For me it's changed everything about my life. I don't even think I'd be acting if I wasn't doing this, or if I hadn't done the first one," he said.

"It's crazy. The character and the whole experience combined for me.

"It's definitely really created something which connects to people on a very fundamental level, it's like primal."

He joked the fans must have a "mental disorder" to camp out in the cold but said it was "really nice" that they had stuck around, especially after five years of the films.

He said: "It's very, very, very cold and I don't understand what kind of mental disorder you have."

Stewart, 22, said: "This is weird, right? I don't know. I'm so happy that every single bit of the story is done.

"Usually we're at one of these premieres going, I don't know, you can't really feel it because you're not done. You're a little desensitised by it all because you have another one coming up.

"This time it's a trip, it is weird."

Meanwhile, Lautner, 20, said the director calling the final cut on his final scene was an emotional moment for all involved.

"My last scene was the slow dance scene between Jacob and Bella. It was an emotional time for all of us."

He also refused to settle the fierce debate among Twi-hards, who divide themselves into 'Team Edward' and 'Team Jacob' camps, in reference to the love triangle at the centre of the saga.

Asked if Bella made the right decision, Lautner said: "To be honest, I don't think she could have gone wrong either way - Jacob and Edward couldn't be more different.

"So yeah, I think she made the right choice but I don't think she would have made the wrong choice if she went with Jacob."

Twilight: Breaking Dawn Part 2 is released in UK cinemas on Friday.
