In its stage version, Zombie Prom was a full-length musical with roughly 22 songs. For the film, a great deal of dialogue and and music were dropped (although the plot is still roughly the same), giving the film a runtime of a slightly over 30 minutes. Among the songs that were dropped are "Rules, Regulations, and Respect" - a song in which Miss Strict teaches the students the principles of discipline, "That's the Beat For Me" - a song in which Eddie Flagrante proclaims his love for his job as a tabloid news reporter, "The Voice in the Ocean" - a duet for Jonny and Toffee in which Jonny explains how and why he came back from the dead (he had been buried at sea in a lead-lined coffin in the stage version), "Case Closed" - a trio for Eddie, Miss Strict, and Jonny in which all three argue about whether or not Jonny should be allowed to re-enroll at Fermi High, "Exposé" - a duet for Miss Strict and Eddie in which they relive their passionate past, and "Forbidden Love" - a duet for Jonny and Toffee in which they reaffirm their love for one another. Plus, there were several other musical moments that were turned into (much shorter) dialogue in the film.
