Evil Dead: The Musical is a Canadian off-Broadway show based on the cult classic film series. This isn't exactly a movie, but it is a professionally shot video document of the Evil Dead: The Musical stage show. Several college students spend the weekend in an abandoned cabin in the woods, accidentally unleashing an evil terror. In this comedic take on the 80s horror franchise, characters and demons sing and dance to songs written specifically for the musical. And, as in the films, Ash is there to dish out his various one liners and fight the never ending Army of Darkness. Audiences are typically warned that the first few rows may get wet as the play calls for large amounts of stage blood to be splattered. The musical takes creative liberty with the plot line of the movies, mixing together the characters and concepts of all three, as well as changing sequences for the sake of the stage and comedic intent.
