The episode, which airs Sunday, is longer than usual, and features a who's who of horror's past and present. Del Toro also managed to throw a few references to his own films in there.
At almost three minutes long, the sequence features nods and references to "Night of the Living Dead," "Pacific Rim," "The 7th Voyage of Sinbad," "The Birds,"
Del Toro didn't direct the full episode, just the opening sequence, but he's the first big name guest director known for his live-action work. Other people who have directed the show's famous couch gag opening include "Ren and Stimpy" creator John Kricfalusi, Oscar-nominated animator Bill Plympton and the mysterious graffiti artist
As in years past, the "Treehouse of Horror" anthology episode will feature three stories, drawing inspiration from other works, including a famous children's tale -- they aren't saying which one -- and Tod Browning's horror classic "Freaks."
