Adaptation Sequence: Movie —> Stage musical —> Movie of musical —> (Extremely) short-lived Saturday morning cartoon show.
Development Gag: As he explains in a documentary about his life and music, Alan Menken's father and many of the other men in his family are dentists — something which he also began to study for but gave up in order to pursue music instead. No doubt he and Howard Ashman had fun writing the dentist's song!
Executive Meddling: The original ending was faithful to the stage musical, with the classic Greek Tragedy arc: Seymour kills his enemy, kills his father-figure, kills his love, then kills himself, and then gigantic Audrey II's go on a Attack of the 50-Foot Whatever rampage and take over the world. After preview audiences lambasted this ending for being "too disturbing", Howard Ashman wrote a happier one.
