What do recent movies The Pacifier, Sin City, Kingdom of Heaven, Monster-in-Law, Star Wars Episode III: Revenge of the Sith, Madagascar, and Fantastic Four all have in common? They all use the Wilhelm Scream, which is a perfect example of the sort of cinematic arcana that I find irresistible. Apparently I'm not the only one: this is one of the few sound effects that actually has a "following," and its fans include Peter Jackson and Quentin Tarantino, not to mention untold legions of sound effects editors. (They seem like a sentimental bunch.)
