In a 1985 interview, Stan Lee cited this movie as the Marvel television project of the 1970s that he wound up giving the most input, and noting he became very friendly with Writer, Executive Producer, and Director Philip DeGuere, Jr. Lee added that next to The Incredible Hulk, this was the live-action adaptation of a Marvel character with which he was most pleased at the time. Lee was disappointed by the movie's low ratings, which he attributed to being aired against Racines (1977).
Morgan LeFay was the first Marvel foe to be adapted to live-action. She was later joined by the Kingpin in Le procès de l'incroyable Hulk (1989), and the Red Skull in Captain America (1990).
Featured in the background of several scenes around the 20 minute mark are scenes from 1948's Abbott and Costello meet Frankenstein.
Morgan LeFay appears as Doctor Strange's foe in this movie. Oddly enough, Morgan LeFay was introduced to the modern era of Marvel comics in Spider-Woman #2 (after an appearance in a dream in Son of Satan #8), just a few months before the air date of this movie, and did not encounter Doctor Strange until Avengers #240-241, published in 1984.
Thomas Lindmer is a replacement for Dr. Strange's comic book mentor, the Ancient One, a native Tibetan who was the former sorcerer supreme.
