Guillermo del Toro's Simpsons Opening: Spot the Reference! To celebrate the latest installment of their long-running Treehouse of Horror episodes - the annual Halloween-themed celebrations of mayhem and gore - Simpsons producers turned to Guillermo del Toro to put his spin on the show's title sequence. The acclaimed director of such modern horror classics as Hellboy, Pan's Labyrinth and The Devil's Backbone - and a diehard Simpsons fan - was more than up to the task. His wondrously entertaining "couch gag" is a densely packed celebration of horror- and sci-fi-cinema. We went through the footage and put together this collection of movies, characters, and real-life persons referenced in this nearly three-minute clip.
