Continuity mistake: Throughout the film Elvira wears her trademark black dress, split to the top of her thigh, and underneath it she always wears black pantyhose. Inexplicably, this changes to black stockings and suspenders when she is undressing for bed on her first night in her new house. (00:31:35)
Other mistake: When Elvira is being chased by her Uncle Vinnie, you can see the hole in his head from where Elvira throws her stiletto at him. However, the hole in his head is apparent 'before' the scene in which she actually throws her stiletto.
Continuity mistake: When Elvira uses her ring to make it rain, the straw around her is burnt black. After Bob unties her and they run off after Vincent, the straw is intact and dry.
Continuity mistake: Gonk's left ear is the one with the ring on it. When Vincent yells at Elvira for not being able to find the cookbook, Gonk growls at Vincent. For that one shot only, the ring switches ears.
Continuity mistake: When Elvira pulls into Fallwell, the hood of her car blows off and lands paint-side-down. When the boys pick up the hood after Elvira asks them for a push, the hood is now paint-side-up.
Continuity mistake: When Elvira is cooking dinner for Bob, she takes the spoon out of the pot, sets the spoon aside, then says her dish looks like "cocka-doodie." When the camera cuts back to the food it looks different, and the spoon is back in the pot. When Elvira puts some spray cheese on the food, the spoon is back where she set it aside earlier.
Revealing mistake: When being chased by her uncle Elvira's hair moves in a way which indicates it's a wig.
Factual error: Right before Elvira is burned at the stake, the officer pronouncing judgement on her says "By the power vested in me, by the sovereign state of Massachusetts..." Massachusetts (according to its own constitution ratified in 1780) is a commonwealth, as are Virginia, Kentucky, and Pennsylvania. Although the internal governments appear to be different, they have the same legal status as states within the United States. (01:17:50)
