All of the visual effects were created on-set and in-camera. Gene Wilder insisted on using the same techniques for visual effects that were used in the 1930s. This also helped to keep the budget down.
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."
Gene Wilder's vision was to suggest black and white in the film's cinematography, but within a color movie.
