Trivia: Halloween III: Season of the Witch
- Actor Allusion: Tom Atkins hopped into bed with a brunette girl he'd only just met in another John Carpenter film.
- Hey, It's That Guy!: Nancy Loomis (Annie from the first film) plays Challis's ex-wife.
- Hey, It's That Voice!: The curfew announcement is read by Jamie Lee Curtis.
- What Could Have Been: If the reception for this one hadn't been so negative, Carpenter might have been able to continue with his original idea of making Halloween an anthology series with a fresh plot and characters for each movie. The only unifying thread would have been that they all take place on Halloween — the possibilities would have been endless.
