In her 1989 book "It's Always Something", Gilda Radner said of this film, "On July 26 (1986), Haunted Honeymoon (1986) opened nationwide. It was a bomb. One month of publicity and the movie was only in the theaters for a week, a box-office disaster."
The film's title is a misnomer, as the couple played by Gilda Radner and Gene Wilder are not newlyweds on a honeymoon, but are about to be married. However, the name of the episode broadcast on radio during the movie was called "Haunted Honeymoon".
The film was Razzie Award nominated for one Golden Raspberry Award for Dom DeLuise for Worst Supporting Actress, and not for Worst Supporting Actor, due to his drag act, and won the Razzie for his role as "Aunt Kate".
According to Gene Wilder's autobiography "Kiss Me Like A Stranger" (2005), it was Hanky Panky (1982), in which he and Gilda Radner, who was married to G.E. Smith at the time, met. The two, quickly became friends, and married prior to this movie.
Location scouting, looking for a suitable mansion, was conducted on the East Coast of the U.S. before locales in England and Scotland were scouted. In the end, the manor chosen was Knebworth House, which is situated about an hour's travelling time from London, England.
According to the October 12, 1984 edition of "The Hollywood Reporter", Gene Wilder bought the picture remake rights to Metro-Goldwyn-Mayer's (MGM's) classic comic-mystery movie "Haunted Honeymoon", a.k.a. "Busman's Honeymoon". Wilder's wife, Gilda Radner, played the part played in the original by Constance Cummings, with Wilder playing the part previously portrayed by Robert Montgomery.
