The only Howling sequel with no character seen in any other Howling entry (Stirba, Werewolf Bitch served as a direct sequel to the first film, with Karen White reviving in her tomb; while 5,6,7 all have Elisabeth She as Mary Lou and other common characters). An oblique reference to the previous two entries occurs when Barry Otto's character asks the Russian woman if other groups of werewolves live elsewhere; she says "Africa....China....maybe California". This may reference the varied groups of werewolves who attended to Stirba in Howling II, and Howling I and II took place in California.
