Mexican film director Guillermo del Toro has been let loose on The Simpsons and directed an eery intro for the show's 24th Treehouse of Horror Halloween episode.

Del Toro, whose films include Blade II and Hellboy, turns the town of Springfield into a place where evil forces have taken over, zombies and monsters reside and nightmares are a reality.

There are around 30 to 40 direct horror movie references in the opening couch gag sequence, including Alfred Hitchcock), Del Toro's 2006 film Pan's Labyrinth and The Shining.
