 Born in Boston, Nazarro entered the movie business during the silent era.He initially worked in two-reelers, honing an approach to filmmaking that was quick, lean and eminently desirable—to producers, at least—before he became a feature film director at Columbia Pictures, beginning with "Outlaws of the Rockies" (1945).Nazarro did the vast majority of his work for Columbia, and was one of the busiest directors on the lot of any major studio—from 1945-55 he worked at a furious pace, directing as many as 13 pictures in one year.
