Mark Sandrich
Trained as a physicist, Sandrich began his career as a prop man in 1922 and five years later emerged as a director of comedy shorts, notably Lupino Lane two-reelers. Sandrich directed his first feature in 1928, but lacking enough experience to handle the technical demands accompanying the advent of sound, he was again consigned to shorts; his highly-regarded, Oscar-winning musical short, "So This is Harris" (1932), which was very playful with both its editing and its soundtrack, enabled him to make another go at features, which he continued to turn out until 1944.
