                 THE MATRIX RELOADED AND THE MATRIX REVOLUTIONS
                         TO BE RELEASED AS IMAX(R) FILMS
             Digitally Re-mastered Using IMAX(R) DMR(TM) Technology

  The Matrix Reloaded to Premiere this Spring; The Matrix Revolutions to Be the
        First-Ever IMAX Day and Date Release of a Hollywood Live-Action
                              Event Film this Fall


LOS ANGELES, CA, April 23, 2003 - IMAX Corporation (NASDAQ: IMAX; TSE: IMAX)
announced today that The Matrix Reloaded and The Matrix Revolutions, the second
and third chapters in the Wachowski Brothers' revolutionary film trilogy, will
be coming to IMAX(R) theatres this spring and fall. The Matrix Reloaded and The
Matrix Revolutions, from Warner Bros. Pictures, Village Roadshow Pictures and
producer Joel Silver, will be digitally re-mastered into the unparalleled image
and sound quality of The IMAX Experience(R), using the revolutionary and
proprietary IMAX(R) DMR(TM) (Digital Re-mastering) technology. The financial
terms were not disclosed.

The Matrix Reloaded: The IMAX Experience will open shortly after the film's 35mm
release on May 15th. And, on November 5th, The Matrix Revolutions: The IMAX
Experience will be released simultaneously on giant IMAX screens in the IMAX
15/70 format and in conventional theatres in the standard 35mm format. This will
mark the first time ever that a Hollywood live action event film is released
concurrently in 35mm and IMAX's format. IMAX's agreement with Warner Bros.
Pictures, which will be the exclusive distributor of the films to IMAX theatres
worldwide, is also the first multiple IMAX DMR film commitment by a major
Hollywood studio.

"We're excited to give fans the opportunity to experience the world of The
Matrix in this spectacular format," said Joel Silver, producer of The Matrix
trilogy. "Throughout the IMAX DMR conversion process, the IMAX team took
meticulous care in maintaining the technical integrity of the films. The IMAX
Experience of both The Matrix Reloaded and The Matrix Revolutions will add a new
dimension to the films' groundbreaking visual action and advances the Wachowski
Brothers' vision for telling the trilogy's story in multiple formats."

"The re-mastered IMAX versions of The Matrix Reloaded and The Matrix Revolutions
provide our audience with a whole new way to experience the films that is even
more immersive and more exciting," said Dan Fellman, President, Domestic
Distribution, Warner Bros. Pictures. "We are very pleased to be able to bring
these two innovative, cutting edge, spectacular motion picture experiences to
the millions of Matrix fans and new audiences at IMAX theatres, and to be taking
part in what we believe is part of the future of cinema. IMAX's dedication and
enthusiasm under the direction of Greg Foster, IMAX's President of Filmed
Entertainment, makes this project not only a landmark in motion picture
distribution, but also a real pleasure, and one that we look forward to
repeating in the near future."

                                                                           .../2

Page 2 "The Matrix always scored among the highest when we asked our consumers what movies they wanted to see re-mastered in IMAX's format, and we believe that the high concept, high tech films will be great for IMAX theatres," said Richard L. Gelfond and Bradley J. Wechsler, Co-Chairmen and Co-CEOs, IMAX Corporation. "We are thrilled to work with Warner Bros. Pictures, Village Roadshow and Joel Silver to bring The Matrix Reloaded: The IMAX Experience to IMAX theatres this spring -- and to be making motion picture history by bringing the first ever day and date release of a live-action event film to IMAX theatres with The Matrix Revolutions this fall. Today, our longtime goal of bringing Hollywood's best event films to IMAX theatres concurrent with the 35mm release, becomes a reality. Warner Bros. Pictures is truly visionary in seeding this new ancillary window through the release of these spectacular films." Warner Bros. Pictures and IMAX will also distribute the first ever 3D motorsports film, NASCAR: The IMAX Experience 3D in Spring 2004.
