He graduated from New York University with a B.A. in English, followed by a Masters in English from Harvard University, and subsequently taught at the University of Missouri from 1916 to 1918. He would have gone on to a professorship, if not for a chance viewing of
The Cabinet of Dr. Caligari (1920), which persuaded him to enter the film business. Initially, he was employed by the Jewish Tribune as a drama and film critic, then as a reader for
Samuel Goldwyn, and as a script clerk for
King Vidor. He joined MGM in 1924, after his first scenario was accepted. He became head of the MGM script department in 1929, and personal assistant to
Irving Thalberg before working as an associate producer on several key MGM films in the 1930s.
