Plot hole: There's no way the gypsy man could have shifted between the three forms of a Dracula look-alike, werewolf, and zombie man so quickly all over the place.
Revealing mistake: After Mr. Maxwell says that the local people refuse to work on the movie, Velma asks why. In her close up, her right pupil is horribly misshapen. Not round, but a wobbly, almost cloud like shape. (00:01:35)

Fred: There's only one problem. How to tell one pair of dummies from the other.

Scooby: Yeah. Rery funny.
Trivia: During the chase scene, there is an advert on the wall which says "H&B Tuna Co." - a reference to Hanna-Barbera.
