Schenck eventually became Loew's right-hand man, helping him manage what rapidly grew into a vast theater chain.
Under Schenck's leadership, the studio produced a great quantity of films, and the studio system allowed it to retain a wide array of talent under its roof: Lon Chaney, Joan Crawford, Jean Harlow, Clark Gable, Spencer Tracy, Katharine Hepburn, Judy Garland, the Jeanette MacDonald-Nelson Eddy team and countless others.
