Factual error: The movie was released in 1986 and is set in "an early year of a decade, not too long before our own." And yet, in the song "Mean Green Mother From Outer Space, " Audrey II sings "you can keep The Thing, keep the IT, keep The Creature, they don't mean shit!" Stephen King's book titled IT was released in 1986.
Continuity mistake: When Audrey II calls Audrey, and throughout the remainder of the film, the wedding dress is completely white. However, when she drops the phone on the floor, the skirt is blue and a different style.
