Fast Company is a 1938 American mystery film directed by Edward Buzzell and starring Melvyn Douglas and Florence Rice as married rare-book dealers who try to solve a murder case. It is based on the novel of the same name by Marco Page. It was followed by two 1939 films featuring the fictional couple, Fast and Loose and Fast and Furious, although different actors played the leads in each of the three films. To avoid confusion with a 1953 MGM film of the same title, Fast Company was retitled Rare Book Murder for television.
