Haunted Honeymoon is a 1986 American comedy horror film starring Gene Wilder, Gilda Radner, Dom DeLuise and Jonathan Pryce. Wilder also served as writer and director. The title Haunted Honeymoon was previously used for the 1940 U.S. release of Busman's Honeymoon based on the stage play by Dorothy L. Sayers.
Wilder and Radner play Larry Abbot and Vickie Pearle, two radio murder mystery actors who decide to get married. Larry, plagued with on-air panic attacks, is treated with a form of shock therapy and subsequently chooses to marry Vickie in a castle-like mansion which had been his childhood home. Once there, they meet the eccentric members of Larry's family, including his great-aunt Kate (DeLuise) and his cousin Charles (Pryce).
Honeymoon was distributed by Orion Pictures through a deal with HBO. The movie flopped by grossing just short of its $9 million budget whilst it was panned by the critics. The movie earned DeLuise the Razzie Award for Worst Supporting Actress. The movie represents the last feature film appearance for Radner (prior to her diagnosis and death from ovarian cancer) and the last directorial role for Wilder.
