Haunted Honeymoon is a 1986 American comedy horror film starring Gene Wilder, Gilda Radner, Dom DeLuise, and Jonathan Pryce. Wilder also served as the film's writer and director. The film also marked Radner's final appearance prior to her death of ovarian cancer in 1989. 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.
In the film, Wilder and Radner play Larry Abbot and Vickie Pearle, two radio murder mystery presenters 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. It was a box office bomb, receiving negative reviews, failing to gain much profit, and earning DeLuise's character of Great-Aunt Kate the Razzie Award for Worst Supporting Actress.
