Jean Marsh, who plays Queen Morgan Le Fay, played a variation of the same legendary character in Battlefield: Part One (1989)/Battlefield: Part Two (1989)/Battlefield: Part Three (1989)/Battlefield: Part Four (1989).
At the time this TV movie first aired on NBC, two of its stars acted on popular NBC sitcoms. Keshia Knight Pulliam was still playing youngest Huxtable daughter Rudy on The Cosby Show (1984), and Michael Gross had finished his tenure playing patriarch Steven Keaton on Family Ties (1982).
The character, Karen that Keshia Knight Pulliam plays is supposed to be twelve years old in the story, yet the real life actress was only ten years old at the time of the filming.
