LOS ANGELES, CA, Sept. 8 /PRNewswire-FirstCall/ - IMAX Corporation (NASDAQ: IMAX; TSX: IMX) and Twentieth Century Fox today announced that The Day The Earth Stood Still, directed by Scott Dickerson and starring Keanu Reeves, Jennifer Connelly, Kathy Bates, John Cleese and Jaden Smith, will be simultaneously released to both IMAX(R) and conventional theatres on December 12, 2008. The film, which is a remake of the 1951 classic sci-fi film about an alien visitor and his giant robot counterpart who visit Earth, will be digitally re-mastered into the unparalleled image and sound quality of The IMAX Experience(R) with proprietary IMAX DMR(R) (Digital Re-mastering) technology.

"The suspense, action and sheer intensity of The Day The Earth Stood Still is ideally suited to IMAX's immersive format," said Bruce Snyder, President, Domestic Distribution, Twentieth Century Fox. "We're very excited to once again expand our relationship with IMAX to offer moviegoers a chance to experience another one of our tent-pole movies in a truly unique and premium way."

"Completing our 2008 slate with this action title is a great way to enter the holiday season and kick off 2009," said IMAX Co-CEO's Richard L. Gelfond and Bradley J. Wechsler. "With the ongoing rollout of IMAX digital theatres, we expect that on December 12th the size of our network will be considerably larger than it is today, which is good for IMAX, exhibitors in the IMAX business, our partners at Fox and, of course, moviegoers."

"We're thrilled to once again be back in business with Fox with another big holiday release," added Greg Foster, Chairman and President of IMAX Filmed Entertainment. "We expect an action-packed film like this to appeal a wide audience, including the elusive tech-savvy 15 - 30 year-old demographic. With crystal clear images, IMAX's powerful digital surround sound and immersive theatre geometry, the earth certainly won't feel like its standing still in IMAX's theatres on December 12th."
