Director Robert Zemeckis loads the first half of What Lies Beneath with humorous cheap thrills (the suddenly ringing phone, etc.) that poke fun at Claire's dilemma while simultaneously making you tense beyond belief. Between each goofy thrill, though, is one true one that will make you jump out of your seat, including a bathtub that keeps filling itself. And all the while, Zemeckis subtly telegraphs the fissures in the Spencers' marriage, slowly revealing that all is not well between these two. Yes, it's a blatant Hitchcock homage to movies such as Rear Window and Suspicion, but it's sleekly made, entertaining and engrossing. Ford does his stoic thing well (and looks great doing it), and Diana Scarwid provides a refreshingly lighthearted turn as Claire's best pal, but it's pretty much Pfeiffer's movie all the way, and she carries the film on her not-so-fragile shoulders. And the third act is a suspense tour de force, complete with a breathtaking sequence featuring Pfeiffer and that menacing bathtub. In a time of obvious horror films, What Lies Beneath is an intelligent, fun thrill ride that will leave you breathless. --Mark Englehart
