Some argue that The Simpsons, which first hit the airwaves in 1989, is past its prime, despite it being one of the greatest TV shows of all time. If you're among those who question whether or not the animated series can still deliver something spectacular, we suggest you take a look at the fantastic opening sequence of this coming Sunday's Treehouse of Horror episode — the show's 24th such homage to Halloween and horror. This year's opener was put together by none other than horror guru and acclaimed director Guillermo del Toro. And, as you might expect, it contains nods to many del Toro films — including Hellboy, Blade, Pan's Labyrinth, The Devil's Backbone, Cronos, and Pacific Rim.

The result in a nearly three-minute opener with references to Edgar Allan Poe, Alfred Hitchcock, Stephen King, the classic Universal monsters, and the cartoon series Futurama. "I ended up cramming in about 1/50th of what I wanted," del Toro says. "To get to do a love letter to two things I love, which is fantasy and horror films and The Simpsons, is great. I enjoyed myself enormously."
