The film was originally filmed in 1993 and released two years later in 1995 which was the Weinstein's M.O. for filming films years before editing them, reediting them and finally releasing them a year or two later.
In a bit of truly inspired foreshadowing, in 1993, two years before this film's release, Christopher Walken played an eerily similar role to that of his portrayal of the Archangel Gabriel in The Prophecy. In the Madonna video for the song "Bad Girl" (from her album "Erotica"), Walken plays the Angel of Death who silently follows a woman (Madonna) as she is being destroyed by her lifestyle. Though there is no speaking part, his mannerisms and look are strikingly similar to his later depiction of Gabriel - even down to his slicked back hair, pale complexion and mostly black wardrobe.
Colonel Arnold Hawthorne is played by Patrick McAllister. Due to the nature of his role and the long gap after It's Alive (1974), McAllister is not credited, but he appears as "special thanks" for his collaboration in the movie, credited as Patrick Kerlee McAllister.
The film was released a year after both Christopher Walken and Eric Stoltz appeared in the Academy Award Winning, Pulp Fiction as both Stoltz and Walken had completed work on that film prior to starting work on this film. The way one can tell is Stoltz's look which he sports in Quentin Tarantino's film.
Features Christopher Walken, Amanda Plummer, and Eric Stoltz. All three appeared in Pulp Fiction the year before although none of them had any scenes together. In this film Christopher Walken shares screen time with both actors.
When Gabriel meets Jerry, the camera's focus moves around Jerry's house. For a brief moment a photo can be seen where appears Jerry with his girlfriend. Although neither she nor her name are ever are mentioned, the woman who appears in the photo with Adam Goldberg is Michele Spadaro, set decorator of the movie. This was her only appearance in a film.
