         IMAX CORPORATION REPORTS FIRST QUARTER 2005 FINANCIAL RESULTS

HIGHLIGHTS

- -     Company beats expectations for the March quarter, reporting net earnings
      of $0.03 per diluted share and a 26% increase in total revenues as the
      Company installs three times as many theatre systems as in the year-ago
      quarter.

- -     Company completes its best nine-month period for signings in eight years,
      which started with the installation of the first IMAX(R) MPX(TM) system
      last June and continued through the March quarter, when the Company signed
      twelve theatre systems, double the year-ago number.

- -     AMC Entertainment, Inc., the second-largest North American exhibitor,
      yesterday signed an agreement to install IMAX(R) theatre systems in five
      domestic multiplexes this year, marking the exhibitor's first-ever deal
      with IMAX.

- -     Company's 2005 film slate is complete, with Harry Potter and the Goblet of
      Fire: The IMAX Experience confirmed as the fourth day-and-date Hollywood
      IMAX DMR(R) release for the year.

TORONTO - May 5, 2005 - IMAX Corporation (NASDAQ: IMAX; TSX: IMX) today reported
first quarter 2005 earnings ahead of expectations, and earlier in the week
delivered two major strategic initiatives regarding the accelerating growth of
its domestic theatre network and the completion of its 2005 film slate. For the
quarter ended March 31, 2005, IMAX reported net earnings of $0.03 per diluted
share, above the Company's previously guided range of breakeven to $0.02 per
diluted share. This compares to a net loss of $0.02 per diluted share reported
for the three months ended March 31, 2004.

"The momentum in our business is undeniable, as we just completed the best
nine-month period for new theatre systems sales since 1997," said IMAX Co-Chief
Executive Officers Richard L Gelfond and Bradley J. Wechsler. "With double the
number of signings and triple the number of installs versus the year-ago
quarter,


                                     Page 4


our first quarter results show that interest in IMAX continues to accelerate
since the introduction of our multiplex-based theatre system last June."

The Company signed agreements for twelve IMAX(R) theatre systems during the
three months ended March 31, 2005, the third consecutive quarter of double-digit
signings. Reflecting the worldwide appeal of The IMAX Experience(R), these
system signings span eight different countries on three continents. The
quarter's signings include a four-theatre agreement with CJ CGV, Korea's leading
commercial exhibitor, as well as deals for new IMAX theatres in commercial
locations in China, India, Kuwait, The Netherlands, Guatemala, Costa Rica, and
the United States.

All of the first quarter agreements were with commercial exhibition customers
and ten were for the Company's newest product, the IMAX MPX system, which allows
for the retrofit of an existing auditorium. While it has been less than one year
since the installation of the first IMAX MPX system, by the end of March the
Company had in place agreements for more than forty of these systems, and nine
are up and running today. Demonstrating the short sign-to-install window enabled
by the IMAX MPX system, Pathe Netherlands, that country's leading commercial
exhibitor, signed, installed and opened an IMAX theatre at its Amsterdam
multiplex during the first quarter.

Subsequent to the close of the quarter, IMAX reached agreement with AMC
Entertainment Inc. to retrofit five domestic multiplexes with IMAX MPX theatre
systems this year. AMC's first two IMAX theatres are scheduled to open in time
for the release of Batman Begins: The IMAX Experience in June, with the
remaining three scheduled to open in September. Under the joint venture
arrangement between IMAX and AMC, the companies will share in both the upfront
cost of the IMAX theatres and also in the ongoing profits generated by these
theatres.

"AMC's entree into the IMAX business marks a major milestone in our domestic
commercial exhibition strategy, and the structure of the deal will allow us to
generate significant additional recurring revenue for our business while quickly
expanding the IMAX network," continued Messrs. Gelfond and Wechsler. "The
addition of AMC not only bolsters IMAX's value proposition to other exhibitors,
but also makes IMAX more attractive to Hollywood studios that want to release
their event films to IMAX's growing network."

Earlier this week, IMAX announced the completion of its 2005 film portfolio. In
November, IMAX and Warner Bros. Pictures will release Harry Potter and the
Goblet of Fire: The IMAX Experience, the fourth in the Harry Potter series, to
IMAX theatres around the world. Last year, The IMAX DMR(R) version of the third
in the series, Harry Potter and the Prisoner of Azkaban, grossed approximately
$14 million throughout the IMAX network. In late November, IMAX expects to
re-release The Polar Express: An IMAX(R) 3D Experience, which broke numerous
records for an IMAX DMR film in 2004, and went on to gross approximately $45
million world-wide. IMAX's 2005 film slate also includes: an original 3D
production to be released in September titled Tom Hanks Presents Magnificent
Desolation: Men Walking on the Moon: An IMAX(R) 3D Experience; IMAX DMR releases
of Warner Bros. Pictures' summer blockbusters Batman Begins and Charlie and the
Chocolate Factory; and the IMAX DMR version of Twentieth Century Fox's animated
feature, Robots, which was released in March.

"Hollywood's level of interest in releasing event films in IMAX's format has
never been higher," concluded Messrs. Gelfond and Wechsler. "Not only is our
full-year film slate in place months earlier than in past years, but our 2006
film portfolio is already starting to take shape, as we engage in discussions
with nearly all of the major studios. Given the tremendous draw of The IMAX 3D
Experience(R), we expect that several of next year's films will be presented in
our unparalleled 3D format."

For the three months ended March 31, 2005, the Company's total revenues were
$31.4 million, up 26% from $24.9 million reported for the prior year period, and
included cash received from the previously announced settlement of litigation
with the former owners of UCI. Systems revenue was $22.1 million versus $16.0
million in the prior year period, as the Company recognized revenue on six
theatre systems, one of which was an operating lease, versus two in the first
quarter of 2004. Film revenue increased by 10% to $4.9 million from $4.5 million
in the same period last year, and Theatre Operations revenue was $3.8 million
versus $3.7 million. Other revenues were $0.5 million in the first quarter of
2005 as compared to $0.6 million in the same period last year. The Company ended
the March quarter with $29.8 million in cash and short term investments as
compared to $29.0 million at the end of December.

Earnings from operations for the three months ended March 31, 2005 increased 34%
to $4.9 million from $3.6 million reported for the same period in 2004. The
Company reported net earnings of $0.03 per diluted share for the first quarter
of 2005, as compared to a net loss of $0.02 per diluted share for the first
quarter of 2004.
