Trivia: There are articles on-line reporting the murder of "Marisela Gonzales", who was shot by her husband in San Pedro on October 11th or 12th, 2020. There are also questions if Marisela, who played "Angela" in "Dangerous Minds" (1985) is still alive. From the police reports, the correct spelling of the 28-year-old woman killed was "Marisela Gonzalez" - ending with a "z", not "s." The Marisela who played Angela was born in 1968, and is currently 52 - so, obviously, not the 28-year-old murder victim.
Trivia: Prince Malagant describes the oubliette where he imprisons Guinevere as just having "walls of air." This is a reference to the fate of Merlin, who was sealed away in a "prison of air."
Trivia: Forest Whitaker plays Cyrus Cole, father of Thomas "Rashid" Cole (Harold Perrineau). In real life, Whitaker is only two years older than Perrineau.
