Trivia: Stan Lee's cameo in this TV movie is actually his first official on-screen Marvel cameo. (Not counting two previous Marvel cartoons to which he served as a narrator.) He would eventually go on to have cameos in over 50 future Marvel film and TV shows, both live-action and animated, either appearing in-person, supplying his voice and likeness, or being seen in photographs. (Plus one animated DC movie.) His final cameo was in 2019's "Avengers: Endgame" - exactly 30 years after this TV movie.
