This movie was inspired by Abbott and Costello Meet Frankenstein (1948), which originally was entitled "Abbott and Costello Meet The Monsters." "Abbott and Costello Meet Frankenstein" was their biggest hit and this movie was The Bowery Boys' biggest hit.
At least three of the characters in this script seem "inspired" by Charles Addams' New Yorker cartoons of the time, collectively known as The Addams Family: Grissom, the Gravesend family manservant, is clearly similar to Lurch; Francesca, the sexy vampire, seems meant to be like Morticia; and, Ellen Corby's creepy Grandma is an awful lot like Grandma Addams.
The 34th of 48 Bowery Boys movies released from 1946 to 1958, and this was the highest-grossing film of the entire series.
Gravesend Manor is set on Long Island, N.Y.
The joke about reading in the dark after going to night school is reused from the East Side Kids movie Spooks Run Wild (1941).
