This television film aired on The Disney Channel every October from 1983 to 1996.
John Schuck would play another Frankenstein monster, Herman Munster, in the late 80s/early 90s on The Munsters Today
The film had a limited VHS release in 1992, re-titled "The Night Dracula Saved the World".
The Werewolf's name derives from Warren Zevon who released the song "Werewolves of London" a year earlier.
Warren the Werewolf is a Hungarian rather than a Welshman like the Wolf Man's alter ego, Lawrence Talbot. For that reason, Igor announces the werewolf's arrival originating from Budapest.
