Utah Jazz Owner Larry H. Miller to Open Utah's First Commercial IMAX Theatre This Fall

TORONTO and SALT LAKE CITY, Aug. 11 /PRNewswire-FirstCall/ - IMAX Corporation (NASDAQ: IMAX; TSX: IMX) and the LHM Group, which is owned by Larry H. Miller, owner of the Utah Jazz, today announced an agreement to open an IMAX(R) theatre at the Jordan Commons Megaplex in Salt Lake City, Utah. The 17-screen Megaplex is the highest grossing site in the state and is one of three successful theatres LHM operates in Utah. The existing Cricket Super Screen 70mm auditorium at Jordan Commons will be retrofitted to house a state- of-the art IMAX theatre and is scheduled to open in Fall of this year. In just over the past four months, IMAX has signed deals to open eight new multiplex- based IMAX theatres in the US, all of which are scheduled to open this year.

"We feel IMAX's digitally re-mastered releases will drive incremental box office and attendance for the Megaplex 17, and we've been very impressed with the amazing per screen averages IMAX theatres generate," said Larry H. Miller, owner of the LHM Group. "We believe IMAX represents a profitable business opportunity, and by offering Hollywood blockbusters in the most immersive format, we're continuing to provide our patrons with an unparalleled moviegoing experience."

"We're excited about the opportunity to partner with Larry Miller and the LHM group to put an IMAX theatre in Jordan Commons - an outstanding location in a key regional market," said IMAX co-Chairmen and co-CEOs Richard L. Gelfond and Bradley J. Wechlser. "Mr. Miller has an impressive track record of success with a wide range of businesses, and his marketing and operations acumen bodes well for the performance of this theatre. We're pleased to add this fantastic site to the growing IMAX theatre network and encouraged by the progress we've made in penetrating new North American markets this year."

LHM Group will retrofit its existing 450-seat large format auditorium into an IMAX theatre and open it to the public this Fall. The theatre is expected to open with the smash hits Batman Begins: The IMAX Experience and Charlie and the Chocolate Factory: The IMAX Experience. In addition to showing Hollywood films digitally re-mastered into the unparalleled image and sound quality of The IMAX Experience(R), the theatre will also exhibit original IMAX and IMAX(R) 3D films, including Magnificent Desolation: Walking on the Moon 3D. Jordan Commons is one of the most popular destinations in Salt Lake City, also featuring numerous restaurants, children's attractions and high-end office space.
