Guillermo Del Toro, who most recently directed “Pacific Rim” is back in the directors chair with the opening to “The Simpsons Treehouse of Terror XXIV.”  Along with nods to his own movies, he gives props to classic monsters like Frankenstein and the Invisible Man.

Blade also makes an appearance, which is awesome because Marvel, which has the rights to the character, could have been all sorts of douchey and said “No,” despite the fact that Del Toro directed “Blade II.”
