Irish quartet U2 rocked the French seaside resort of Cannes early on May 20, prior to the premiere of its three-dimensional concert film.
Titled U2 3D, the full-length movie was shot in South America during the band's 2006 "Vertigo" tour.
Producer John Modell said the digital production heralds a new wave of three-dimensional filmmaking. "We are replicating the physiology of sight," Modell said. "If you get it off by just a hair it creates actual physical problems - eye strain, nausea. We don't have that at all."
The production will only be shown in 3D. At present, about 700 screens are equipped with the Real D 3D system on which the film will initially show. Most are in the United States.
Real D chairman Michael Lewis predicted the number will soon rise to 1,000 worldwide.
