News Release: Third Installment of Harry Potter Film Series to Be Released As IMAX(R) Film In Summer 2004

IMAX Corporation (Nasdaq: IMAX; TSX: IMX) and Warner Bros. Pictures today announced that Harry Potter and the Prisoner of Azkaban, the third installment of the Harry Potter film series, will be released to IMAX(R) theatres in addition to conventional theatres in June 2004. This family event film, based on the third book of the world renowned and best-selling series, will be digitally re-mastered into the unparalleled image and sound quality of The IMAX Experience(R) through proprietary IMAX(R) DMR(TM) (Digital Re-mastering) technology. This deal represents the second IMAX DMR film commitment from Warner Bros. Pictures in the last year, and comes on the heels of the successful performances of the second and third chapters of The Matrix trilogy in IMAX theatres. Based on the best-selling series of books by J.K. Rowling, the first two movies in the Harry Potter series broke worldwide records with a combined box-office gross of nearly $1.9 billion. Warner Bros. Pictures is to be the exclusive distributor of Harry Potter to IMAX theatres worldwide.

'Our partnership with IMAX has been extremely rewarding and has allowed our films to expand their reach beyond our traditional audiences by offering viewers a whole new way to see Hollywood event films that is uniquely immersive and exciting,'said Dan Fellman, President, Domestic Distribution, Warner Bros. Pictures. 'We are so pleased that this summer, Harry Potter and the Prisoner of Azkaban, which lends itself beautifully to IMAX's format, will play throughout the IMAX theatre network. Besides Harry Potter and The Prisoner of Azkaban, we are discussing an IMAX(R) 3D release of Polar Express in November 2004, and an IMAX DMR release of Charlie and the Chocolate Factory in the summer of 2005.'

'We are thrilled to be expanding our mutually beneficial partnership with Warner Bros. Pictures that began with the successful release of the last two chapters in The Matrix trilogy,'said Richard L. Gelfond and Bradley J. Wechsler, Co-Chairmen and Co-CEOs, IMAX Corporation. 'This announcement is yet another indication that we are achieving our goal of bringing the very best Hollywood event films to IMAX theatres, which we believe is key to expanding the IMAX network around the world. Our research has shown us that moviegoers want to see blockbuster films in IMAX's format and are paying a premium price for the experience. We believe that the magic of Harry Potter The Prisoner of Azkaban will translate into an amazing cinematic adventure in IMAX theatres, and will continue the strong performances of IMAX DMR releases to date.'

'We are very excited to bring the adventure and fantasy of Harry Potter to life on the giant IMAX screen,'said David Heyman, producer of the Harry Potter film series. 'When Alfonso Cuaron, the film's director, and I, saw IMAX DMR, we knew we had to release this film in IMAX theatres, as it will bring a whole new perspective to this magical story. Whether they've read all of the Harry Potter novels and seen the first two films, or are just now immersing themselves in the world of Harry Potter, fans will amplify their experience with IMAX's exceptional and immersive cinematic presentation.'

Warner Bros. Pictures and IMAX will also be distributing the first-ever 3D motorsports film, NASCAR 3D: The IMAX Experience starting March 12, 2004. Narrated by Kiefer Sutherland and starring the drivers of NASCAR, NASCAR 3D: The IMAX Experience will put moviegoers in the driver's seat in an unprecedented way through the magic of IMAX 3D technology.
