U2's new concert film 'U2 3D' premiered at the Sundance Film Festival in Park City, Utah on Saturday night.

Speaking to the Associated Press before the screening, U2 guitarist The Edge said: "I was really hoping we weren't crap after all these years. Luckily we weren't."

He was joined at the screening by singer Bono, drummer Larry Mullen and bassist Adam Clayton.

Commenting on seeing himself in 3D on a cinema screen, Bono said: "It's kind of horrific. It's bad enough on a small screen. Now you get to see the lard arse 40-foot tall."

The film, which is the first digital 3D, multi-camera, real-time production, will be shown at Cineworld, Movies at Dundrum and Movies at Swords - all in Dublin - from 22 February. It will also be screened at SGC Dungarvan in Co Waterford.
