The director of Pan's Labyrinth and Hellboy has put his talents to the production of a cartoon love-letter to the sci-fi/horror genre, helping the Simpsons team put together a three minute title sequence for the forthcoming Treehouse of Horror special.
Del Toro was asked to riff on his own movies, but decided to share the love with other film-makers, leading to a madcap dash through horror history that stuffs almost every legendary villain and monster into an extended version of the show's familiar first minute.
Season 24 of the Simpsons, the longest running show on TV, is currently being broadcast on Sky One.
Are there any classic characters del Toro missed out? Or did you notice any personal favourites?
