When Rachel goes to the window in her bedroom, the crucifix is shown outside of her nightgown, but when she leans out the window the crucifix isn't shown, then it is when she goes back in the bedroom.

Before Meiermann interviews Doctor Rev. Whitfield,there is an establishing shot of the front of the residence where they meet. The sign that hangs outside indicates that the house belongs to Dr. Paul Beecher, Phyisican Surgeon, but there is no Dr. Paul Beecher in "The Return of Dracula."

The shot is up momentarily, but it is clearly a shot from "The Vampire."
