For at least two decades, musical theater has been adapting existing intellectual properties that have had cultural impact with teen audiences, such as Hairspray, Mean Girls, and the recent production of Beetlejuice. Heathers the Musical, a 2014 iteration of Daniel Waters’s 1988 film, is one of those that found new life through song. With book, music, and lyrics written by Kevin Murphy and Lawrence O’Keefe, the musical took the film’s signature sardonic humor to new heights during its original Off-Broadway run.
