Like a roller coaster ready to fly off its rails, Van Helsing rockets to maximum velocity and never slows down. Having earned blockbuster clout with The Mummy and The Mummy Returns, writer-director Stephen Sommers once again plunders Universal's monster vault and pulls out all the stops for this mammoth $148-million action-adventure-horror-comedy, which opens (sans credits) with a terrific black-and-white prologue that pays homage to the Universal horror classics that inspired it. The plot pits legendary vampire hunter Van Helsing ) against Dracula (the deliciously campy ), his deadly blood-sucking brides, and the Wolfman () in a two-hour parade of outstanding special effects (980 in all) that turn Sommers' juvenile plot into a triple-overtime bonus for CGI animators. In alliance with a Transylvanian princess () and the Frankenstein monster (Shuler Hensley), Van Helsing must prevent Dracula from hatching his bat-winged progeny, and there's so much good-humored action that you're guaranteed to be thrilled and exhausted by the time the 10-minute end-credits roll. It's loud, obnoxious, filled with revisionist horror folklore, and aimed at addicted gamers and eight-year-olds, but this colossal monster mash (including Mr. Hyde, just for kicks) will never, ever bore you. A sequel is virtually guaranteed. --Jeff Shannon
