|Died||23 September 1961 (aged 62)|
In 1926 Heinrich Nebenzahl and director-producer Richard Oswald founded the company Nero-Film. As head of this company Seymour Nebenzal became one of the most important producers of the transition period from silent to sound film in Germany. He worked with the directors Georg Wilhelm Pabst, Arthur Ripley, Douglas Sirk, Harold S. Bucquet, Edgar G. Ulmer, Léonide Moguy, Paul Czinner and Fritz Lang among others.
In 1939 he went on to Hollywood where he became one of the first independent producers. He made films with Edgar G. Ulmer, Douglas Sirk, Léonide Moguy, Arthur Ripley, and Albert S. Rogell. He produced remakes of his successes from the early 1930s: Siren of Atlantis with Maria Montez and M (1951), that was directed by Joseph Losey.
In October 1946 he paid $150,000 for the world rights to Madame Butterfly.
He died of a heart attack at his Munich home.
Associate producer of M (1951) was his son Harold Nebenzal (31 March 1922 in Berlin – 14 February 2019 in Los Angeles) who became a script writer (The Wilby Conspiracy), film producer (Cabaret, Gabriela) and novelist (Cafe Berlin). Harold was in charge of foreign film production for many years for MGM, and also worked on many of the films of Billy Wilder including Fedora; Wilder was Harold Nebenzal's closest friend for 30 years. Seymour had years earlier made possible Wilder's first film, People on Sunday, by borrowing the needed funds to make the picture from his father, Heinrich Nebenzahl, the first in the line of three Nebenzal motion picture producers.
