                  ACQUISITION OF METRO-GOLDWYN-MAYER COMPLETED

                    MGM Names New Senior Management Team


Los Angeles, April 8, 2005 - Metro-Goldwyn-Mayer Inc. (MGM) announced today that
a consortium comprised of Sony Corporation of America, Providence Equity
Partners, Texas Pacific Group, Comcast Corporation (Nasdaq: CMCSA, CMCSK) and
DLJ Merchant Banking Partners completed its acquisition of the Company. This
transaction establishes MGM as one of the world's largest privately held,
independent motion picture, television and home video companies.

"Today we begin a new, exciting chapter in the life of MGM," said Dan Taylor,
President of MGM. "With our strong financial and strategic partners, we look
forward to building on MGM's exceptional legacy and capitalizing on emerging
technologies and markets to provide consumers worldwide more opportunities to
enjoy the world's largest modern library of films and television programming. We
look forward to a very bright future for MGM."

MGM also announced today several key senior management appointments. Charles
Cohen will serve as Executive Vice President of the Company. Mr. Cohen had
served as Executive Vice President of Finance and Corporate Development at MGM
since May 1997. Jim Packer will serve as Executive Vice President of Television
Distribution. Mr. Packer had served as Executive Vice President, Television

Vice President of Home Entertainment Distribution. Mr. Thomas served previously
as Executive Vice President of Worldwide Marketing since 2000. Bruce Tuchman has
been appointed Executive Vice President of MGM Networks. Mr. Tuchman had served
as head of MGM Networks since July 2001. Travis Rutherford has been named
Executive Vice President of Consumer Products and Location-Based Entertainment.
Mr. Rutherford had served as Senior Vice President of MGM's Consumer Products
Interactive since January 2001.

Going forward, MGM expects to benefit from operating agreements with Sony
Pictures Entertainment (SPE) under which SPE will assume certain distribution
responsibilities for MGM's library of 4,000 films and 10,400 television episodes
through SPE's global distribution network, which currently distributes SPE's
library of 3,500 films and 35,000 television episodes. In addition, MGM expects
to co-finance new films with SPE and co-produce some of these new projects.
These films will be distributed and marketed by SPE. MGM will continue to
develop new original television programs and is currently completing production
on the ninth season of Stargate SG1 and the second season of Stargate Atlantis,
which will both premiere this summer. Sony Pictures Television will assume
production management for certain MGM television content.

In addition to the operating agreements with SPE, MGM also expects to benefit
from distribution agreements with Comcast. MGM content will be available on
Comcast's video on demand platform and on new cable channels operated by Comcast
and jointly owned by Comcast, SPE and the members of the consortium.

Films currently slated for release by MGM will proceed on schedule. The Company
expects to release The Amityville Horror on April 15 and Into the Blue, Romance
and Cigarettes, The Woods, The Pink Panther and Art School Confidential in the
fall of this year.

MGM and the consortium announced on September 23, 2004 that they had entered
into an agreement related to this acquisition. The agreement was adopted by MGM
shareholders on December 17, 2004. In accordance with the terms of the
agreement, stockholders of MGM will receive $12.00 in cash, without interest,
for each MGM share held.
