Double Door is a 1934 American pre-Code thriller film directed by Charles Vidor, written by Jack Cunningham and Gladys Lehman, and starring Evelyn Venable, Mary Morris, Anne Revere, and Kent Taylor. The film follows a young bride who finds herself tormented by her wealthy husband's abusive spinster sister in their New York City mansion. It is based on the 1933 Broadway play of the same name by Elizabeth A. McFadden and was billed in the opening credits as "The play that made Broadway gasp". Both Morris and Revere reprised their Broadway roles in the film. Though Morris had a long stage career, this is her only film performance.
