           ICAHN QUESTIONS ANTIOCO'S THREAT TO RESIGN FROM BLOCKBUSTER

April 28, 2005, New York, NY. -- Carl Icahn  announced  today that he is sending
the following  letter to  stockholders of Blockbuster  concerning Mr.  Antioco's
threat to resign from Blockbuster if he is not elected as a director:

                                  CARL C. ICAHN
                          767 Fifth Avenue - 47th Floor
                               New York, NY 10153

April 28, 2005

Dear Fellow Blockbuster Stockholder:

We  are  engaging  in a  proxy  contest  with  Blockbuster  management  and  are
attempting to elect Edward  Bleier,  Strauss  Zelnick and me to the  Blockbuster
Board of Directors at the upcoming  annual meeting of  Blockbuster  stockholders
scheduled for May 11, 2005.


WHY IS MR. ANTIOCO SO AFRAID THAT WE WILL GET ELECTED THAT HE IS BLACKMAILING
YOU TO VOTE FOR HIM?

Mr. Antioco announced yesterday that if he is not reelected to the Board he will
quit the  Company and the  Company  indicated  that he would then be entitled to
receive  his full  compensation  package  which is reported to be worth over $50
MILLION.  WHY WOULD THE  COMPANY  CONCEDE  THAT ISSUE?  We have been  advised by
counsel  that if he uses the fact  that he is not on the  Board as an  excuse to
resign, the Board would have 10 business days to cure the default.  During those
10  business  days,  the Board  could  create a new  Board  seat and elect him a
director, a move we would support and would prevent him from having an excuse to
resign and thereby get his egregious  compensation  package.  WE DON'T THINK MR.
ANTIOCO WILL LEAVE WITHOUT HIS OUTRAGEOUSLY LARGE COMPENSATION PACKAGE.


WHY IS MR. ANTIOCO AFRAID THAT OUR THREE NOMINEES WILL BE ELECTED?

Because,  if we elect all three of our nominees,  then Mr. Antioco  becomes much
more accountable for his performance.  If stockholders are dissatisfied with Mr.
Antioco's  performance  during  the next  year,  they will have the  ability  to
nominate  enough  directors  who,  combined  with  our  three  directors,   will
constitute  a majority  of the Board in 2006.  That Board will have the right to
hire new management.


WHY SHOULD STOCKHOLDERS SUPPORT MY FULL SLATE?

If my slate is elected the nominees will comprise a minority of the Board.  As a
result,  we understand  that we will not be operating the Company.  Indeed,  Mr.
Antioco  has  spoken  about his plan for the  Company.  We have no  preconceived
opinion regarding his plan. We are not seeking to micromanage or even manage the
Company,  but only to be strong  advocates for the  stockholders on the Board of
Directors.  We are obligated to act as fiduciaries for all the stockholders.  AS
FIDUCIARIES,  WE WILL  ATTEMPT  TO CURB  ANY  EXCESSIVE  EXECUTIVE  COMPENSATION
SCHEMES AND TO COUNSEL  MANAGEMENT  AGAINST WHAT WE MAY DEEM TO BE ILL-CONCEIVED
BUSINESS  PLANS THAT WASTE THE COMPANY'S  ASSETS.  We will use our best judgment
about what is in the best interest of stockholders.  However, we will not be the
rubber-stamp directors that it is obvious Mr. Antioco desires.


WHO ARE OUR NOMINEES?

I  chose  Mr.  Bleier  and  Mr.  Zelnick  as my  co-nominees  because  they  are
well-respected  entertainment  industry  veterans,  who, if elected,  will bring
their life long industry  experience  to bear on the issues facing  Blockbuster.
Mr.  Bleier  recently  retired,  after 34 years of  service,  from  Warner  Bros
Entertainment Inc., where he had been president of the division  responsible for
marketing of movies,  animation  and TV programs.  Prior to that he was a senior
executive of ABC-TV. He is presently a director of Real Networks Inc., a leading
company in Internet  streaming of audio and visual media. Mr. Zelnick is founder
of Zelnick Media LLC, an investment and advisory firm  specializing in media and
entertainment.   He  was   President   and  Chief   Executive   Officer  of  BMG
Entertainment,  at that  time a $4.7  billion  music and  entertainment  unit of
Bertelsmann  A.G.,  where  he  managed  one of the  world's  largest  music  and
entertainment  companies,  one of the leading music publishing companies and the
world's  largest  record club.  Previously,  Mr. Zelnick was President and Chief
Operating  Officer of 20th  Century Fox that was engaged in the  production  and
distribution of feature films and television programming.

IS IT  IMPORTANT  TO ELECT ALL THREE OF THE  NOMINEES ON OUR SLATE,  RATHER THAN
JUST TWO?

Election  of three  stockholder  nominated  directors  at this time will help to
insure that  management is held  accountable to its business plan. If they fail,
stockholders  will have the  opportunity  next year to  nominate  and elect more
directors  and if they do so there  would be a  majority  of  directors  who are
stockholder  nominees.  If you only  elect two of our  nominees,  it will not be
possible to ensure a majority of stockholder nominees after next year's election
of directors.  THE POSSIBILITY OF A STOCKHOLDER  NOMINATED MAJORITY OF DIRECTORS
IN  2006  IS  WHAT  WILL  FURTHER  INCENTIVIZE  MANAGEMENT  TO DO ITS  BEST  FOR
STOCKHOLDERS.

I believe that true stockholder democracy involves stockholders expressing their
rights and that  elections of corporate  boards should be more than a coronation
process for board members' self  perpetuation  through  self-nomination.  I URGE
STOCKHOLDERS TO VOTE FOR EACH OF THE THREE MEMBERS OF MY SLATE.

                                                              Very truly yours,

                                                                Carl C. Icahn

filed by Mr. Icahn and his affiliates in connection  with their  solicitation of
proxies from  Blockbuster  stockholders.  Stockholders  of Blockbuster and other
interested  parties may obtain,  free of charge,  copies of the definitive proxy
statement and any other documents filed by Mr. Icahn and his affiliates with the
