Burbank, CA, March 31, 1998 -- Shareholders of Iwerks Entertainment, Inc.
(NMS:IWRK) today rejected the company's proposed merger with Showscan
Entertainment Inc. (NMS:SHOW) in a vote announced at Iwerks' annual meeting of
shareholders.

"We are disappointed with the results, but are still prepared to move forward
with our strategy and plans for growing Iwerks," said Charles Goldwater,
Chairman and Chief Executive Officer of Iwerks.  "The tactics and timing of
results may change as a result of this vote, but our mission -- to firmly
establish this company as a full-service provider of entertainment attractions
- -- remains the same."

He added, "In pursuing our goals, we will be responsive to the concerns of our
stockholders who have spoken today through their votes."

Mr. Goldwater said that Iwerks' future "begins with looking at the company from
an expanded perspective -- as an entertainment company built on a strong
foundation of superior hardware and technology."  He cited five specific areas
of strategic emphasis for the company moving forward: 

- --  improving cost efficiency;

- --  accelerating and expanding sales activities;

- --  improving the quality of and investment return on Iwerks' film assets;

- --  extending the Iwerks brand through stepped-up marketing efforts;

- --  strengthening the company's management ranks.

"There are certainly a number of challenges looming ahead, but we already are
moving aggressively to make good things happen," he said.

With respect to the other business before the shareholders' meeting, Mr.
Goldwater was elected to the Board of Directors to serve a three-year term, and
proposed amendments to Iwerks' stock option plan were defeated.
