Director Kevin McDonagh often likes to put nods to his previous film in his work. There are two references to Idol of Evil in Lycanthropy: 1. The doctor David Hilton is the same name as the hero in Idol. 2 the Victim of the vampire sisters in the bar is called Bain and is played by the actor who played the same character in Idol of Evil.
The hero's wife is called Tessa Taylor and that is the name of the News reporter in McDonagh's follow up feature Enter the Cage./
The book the detective reads on werewolves is the same book used in the game Gabriel Knight II: The Beast Within.
