Research Conducted at New IMAX(R) MPX(TM) Retrofit Locations Shows Excellent Consumer Response to The IMAX Experience(R)

NEW YORK, NY, Dec. 9 /PRNewswire-FirstCall/ - IMAX Corporation (NASDAQ: IMAX; TSX: IMX) and National Amusements Inc., North America's sixth largest theatre operator, today announced that newly-opened National Amusements' IMAX(R) theatres timed to the release of Warner Bros. Pictures' The Polar Express: An IMAX 3D Experience are posting impressive box office results and high customer satisfaction ratings during their first month of operation. The four new sites are located at multiplexes in White Plains, NY; Buckland Hills, Connecticut; Louisville, Kentucky; and Springdale, Ohio, and all feature IMAX(R) MPX(TM) theatre systems, which were specifically designed to make it easier for exhibitors to retrofit existing 35mm multiplex auditoriums into IMAX theatres. National Amusements installed the new IMAX MPX theatre systems within three months of signing its agreement with IMAX, and since opening to the public on November 10th, the exhibitor has seen four consecutive weekends of sold-out and near-capacity shows.

Exit poll research conducted at National Amusements' newly opened IMAX theatres during their opening weekend showed that of those surveyed:

    -  93% were extremely or very satisfied with The IMAX 3D Experience(R)
    -  90% are extremely or very likely to recommend seeing
       The Polar Express: An IMAX 3D Experience
    -  Half are extremely or very likely to see the film in an IMAX theatre
       again
    -  84% say the addition of the IMAX theatre has improved their perception
       of the theatre
    -  86% are more likely to visit the multiplex again in the near future
       because of the addition of an IMAX theatre

"We have been very pleased with the performance of our four new IMAX theatres," said Shari E. Redstone, president, National Amusements, Inc. "The arrival of IMAX MPX technology, using the IMAX large format theatre systems in several of our multiplexes, has enabled us to provide yet another premium cinematic experience within our theatres - which are already known for their superior sight and sound."

"National Amusements has been an early adopter of the new IMAX MPX theatre system, using it as a way to reinvest in some of its top performing multiplexes, differentiate its theatres from nearby competitors, and offer patrons a whole new way to experience Hollywood films," said IMAX's Co-Chairmen and Co-CEO's, Richard L. Gelfond and Bradley J. Wechsler. "These new IMAX MPX theatres have performed extremely well thus far and we congratulate National Amusements on this success. We believe that the combination of great early box office returns and highly satisfied moviegoers bodes well for future National Amusements' IMAX theatre openings."
