Prolific director Bryan Singer takes a turn towards horror as the producer of this Halloween shocker directed by X2 and Superman Returns screenwriter Mike Dougherty. With four interwoven tales concerning a high-school principal who moonlights as a vicious serial killer, a college-age virgin who’s saving herself for that special someone, a woman whose hatred of Halloween is only exceeded by her husband’s love of the mischievous holiday, and a callous group of teens who carry out an unforgivably cruel prank, this fall frightener mixes Tarantino-style storytelling with the kind of chills that can only occur on the darkest day of the year.
