Everyone is arriving at the Sundance Film Festival ready for the premiere of 'U23D' tonight. Last night the audio and visual tech teams were on site at the Eccles Theater to test the systems. In the house were 'U23D' Producer and Executive Audio Producer, John Modell as well as U2's long-time sound team, Carl Glanville and Robbie Adams, Audio Director, Joe O'Herlihy, VFX Supervisor, Dave Franks, Dolby's Technical Director Russell Allen, Production Manager Jenny Sireci, and Supervising Producer, Ted Kenney. Why such a big crew for the premiere of a film ? 'We brought all the guys who have worked with the band a long time and Clair Bros who brought a customized sound system to the theater.' explained John Modell. ' We also worked with Dolby who delivered their newest 3D system, which is amazing looking.' It is, he added, 'the most high tech film screening that's ever been done in history.' U2.Com will be bringing news from Sundance over the weekend. Keep checking in.
