Monster Mash (also known as Monster Mash: The Movie and Frankenstein Sings) is a 1995 musical comedy horror film written and directed by Joel Cohen and Alec Sokolow, based on Bobby Pickett's 1962 novelty song "Monster Mash" and the 1967 stage musical, I'm Sorry the Bridge is Out, You'll Have to Spend the Night, also by Pickett and Sheldon Allman. The film adaptation follows Mary and Scott, a young couple who find themselves spending Halloween night at the mansion of Dr. Victor Frankenstein. Along with housemates Igor, Count Dracula, Wolfie, Frankenstein's monster, and a reanimated Elvis Presley, Dr. Frankenstein takes a personal interest in what secret designs await the main characters.
