Double Door is a 1934 American pre-Code thriller film[2] directed by Charles Vidor, written by Jack Cunningham and Gladys Lehman, and starring Evelyn Venable, Mary Morris, Anne Revere, and Kent Taylor.

[3][4] In 1910 Manhattan, Victoria Van Brett is a bitter, domineering spinster who lives an isolated life with her half-sister, Caroline, in the palatial mansion built by their late industrialist father.

Mortimer reverts the family will back to Rip, and blackmails Victoria with her attempted murder of Anne, threatening to report her to police if she does not sign the will.

[5][6] The characters of Caroline and Victoria Van Brett were both loosely based on the last-surviving sisters of the Wendels, a powerful New York City family who resided in a large mansion together (seven siblings in total, all unmarried) in isolation for most of their lives.

[7][8] Filming was to begin in January 1934 but Paramount waited until lead actress Mary Morris, who was playing in the stage version in Philadelphia, had finished her engagement and could join the production team in Hollywood.

[9] The New York Times review was favorable: "The film version of Miss McFadden's play is a careful and intelligent copy of the original.

"[3] Morris was praised for her "highly effective performance", while "Evelyn Venable, as the young wife, and Anne Revere, as the sister (the part she played on the stage), are admirable foils for the cruel old witch.

Paramount tried to sign her for additional films, but Morris was unimpressed by the Hollywood scene and returned immediately to the stage, where she continued to tour the New England states in Double Door during the summer of 1934.
