Zac Efron Overwhelmed By Fans In London

The 21-year-old actor was greeted by the deafening shrieks of his young admirers when he arrived at the UK premiere of his new film ‘17 Again’ in London’s Leicester Square last night (26.03.09).

Zac - who rose to fame in Disney’s teen hit ‘High School Musical’ - spent half an hour signing autographs and posing for picture with fans, who overwhelmed him with their enthusiasm and volume.

Speaking about his warm welcome, the actor told BANG Showbiz: “It’s insane. This is the biggest one yet. It’s so crazy.”

In the film, Zac plays the younger self of Mike O’Donnell, a frustrated businessman who gets the chance to be 17 again and change his life.

But if the same thing happened to Zac, he insists he wouldn’t alter his life.

He said: “It’s all going pretty well so far. I wouldn’t do anything differently.”

When it comes to the film, Zac is nervous about how it will be received.

He added: “I can’t wait to see what everybody thinks. It’s definitely different, but this is a movie to bring along the fans, I didn’t do anything too different.”

Asked if he would be prepared to do a full frontal nude scene, Zac said: “You look so excited. I don’t know. Honestly, I don’t know.”

Nude or not, the young star is determined to get rid of his clean-cut image and move into different roles.

He said: “Most of the directors I’d want to work with don’t even know who I am. Their daughters might.”

‘The X Factor’ star Diana Vickers, ‘Harry Potter’ actors Tom Felton and Bonnie Wright, glamour model Danielle Lloyd and ‘High School Musical’ actress Jemma McKenzie-Brown also attended the premiere.
