Samuel Marx (January 26, 1902, New York City – March 2, 1992, Los Angeles) was an American film producer, screenwriter and book author.
During the 1950s he began working as an executive producer for Desilu Productions, where he was responsible for films and shows such as The General Electric Hour.
One such show, the TNT special series MGM: When the Lion Roars, was telecast in 1992 during the month Marx died of heart failure at age 90.
The next day, Marx was among the studio executives who were told by Louis B. Mayer that, to avoid scandal, the death would have to be ruled "suicide because of impotence".
He concluded that Louis B. Mayer and Howard Strickling, MGM's head of publicity, with Irving Thalberg's collusion, had ordered the evidence be tampered with before the police arrived.
