     This  Amendment  No. 15 amends the Statement on Schedule 13D filed with the
Securities and Exchange Commission on March 7, 1993 by Blockbuster Entertainment
Corporation ("BEC"), Blockbuster Pictures Holding Corporation ("Holdings"), SEGI
Holding  Company  ("SEGI")  and  Repinvesco,  Inc.  ("REPI"),  as  amended  (the
"Statement").  This  Amendment  No. 15 is filed  with  respect  to the shares of
common  stock,  par value  $.001 per share (the  "Common  Stock"),  of  Spelling
Entertainment  Group  Inc.  (the  "Issuer"),  a Delaware  corporation,  with its
principal  executive  offices located at 5700 Wilshire  Boulevard,  Los Angeles,
California  90036.  Capitalized  terms  used  but not  defined  herein  have the
meanings assigned to such terms in the Statement.

Item 2. Identity and Background.
        -----------------------

     Item 2 is hereby amended and supplemented as follows:

     On July 31, 1996, Viacom Inc. ("Viacom")  contributed the stock of Holdings
to Viacom  International Inc. ("Viacom  International"),  a Delaware corporation
and a wholly owned subsidiary of Viacom.  Viacom  International is a diversified
entertainment and publishing company whose executive offices are located at 1515
Broadway, New York, New York 10036.

     National  Amusements,  Inc., of which Sumner M. Redstone is the controlling
shareholder,  owns  approximately 67% of the voting stock of Viacom. The current
list of executive officers and directors of Viacom  International and Viacom are
reported on  Schedules  I and II hereto,  respectively.  Each  person  listed in
Schedules I and II is a United States citizen.  During the past five years, none
of  Reporting  Persons nor any person  named in  Schedules I and II (i) has been
convicted in a criminal  proceeding  (excluding  traffic  violations  or similar
misdemeanors)  or (ii) has been a party to a civil  proceeding  of a judicial or
administrative body of competent  jurisdiction and as a result was or is subject
to a  judgment,  decree  or final  order  enjoining  future  violations  of,  or
prohibiting  or mandating  activities  subject to,  federal or state  securities
laws, or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or other Consideration.
        -------------------------------------------------

     Item 3 is hereby amended and  supplemented as follows:  Purchases of Common
Stock  pursuant to the program  described  in Item 4 will be made using  working
capital of Viacom International.

Item 4. Purpose of Transaction.
        ----------------------

     Item 4 is hereby amended and restated in its entirety as follows:



                                  Page 5 of 16





     On April 18, 1997,  Viacom  announced  its intention to pursue a program to
purchase, from time to time in the open market, such number of additional shares
of  Common  Stock  as  may be  necessary  to  increase  the  Reporting  Persons'
percentage  ownership of the Issuer from approximately 75% to approximately 80%,
thereby  permitting tax  consolidation of the Issuer with Viacom.  The Reporting
Persons expect that Viacom will complete such  purchasing  program by the end of
1997.  Except as  described  in this Item 4 and as may be  necessary to maintain
their  percentage  ownership in the Issuer at  approximately  80%, the Reporting
Persons have no present intention of engaging in any of the transactions  listed
in clauses (a) through (j) of Item 4 to Schedule 13D.


     A copy of the press  release by Viacom,  dated April 18, 1997,  relating to
the above-described stock purchase program is attached hereto as Exhibit 99.1.

Item 7. Material to Be Filed as Exhibits.
        --------------------------------
