BURBANK, CA, March 26, 1998--Iwerks Entertainment, Inc. (NMS:IWRK)
said today that it continues to support its proposed merger with
Showscan Entertainment Inc. (NMS:SHOW), and urged shareholders to
vote their proxy ballots in favor of the merger.  The company said
that while it was disappointed by today's announcement by one of
its shareholders, Heartland Advisors Inc., that Heartland would
oppose the transaction, it is continuing to meet with and contact
shareholders to explain the benefits of the merger. 

Iwerks said that it stands behind its previously stated position
that "this merger is strategically significant to Iwerks and that
the benefits are considerable."  In presentations to shareholders
this week, Iwerks' management has presented in significant detail
its integration plan and business strategy, as well as financial
projections that illustrate the positive effect the merger would
have on the value of its stock. 

The company cited a report issued Wednesday by Institutional
Shareholders Services (ISS) a leading proxy analysis firm, that
said the merger warrants shareholder support.  "ISS's objectivity
in this case is significant.  They listened, as have we, to the
concerns of certain shareholders who have publicly stated their
opposition to this transaction, then they listened to our detailed
presentation of the facts and our plans for the future of Iwerks. 
In the end, they recommended that our shareholders support the
merger." 

Both Iwerks' and Showscan's Board of Directors have unanimously
approved the merger and recommend that shareholders vote in favor
of it.  Iwerks' shareholder meeting to vote on the proposed merger
and other matters will be held at 10:00 a.m. local time on
March 31, 1998 at Iwerks' offices, 4540 West Valerio Street,
Burbank, California.
