In this action-packed disaster film set in America's heartland, an ex-husband-and-wife team of storm chasers rushes to be the first to study the dynamics of tornados with some fascinating new technology. Though Helen Hunt (AS GOOD AS IT GETS) and Bill Paxton (APOLLO 13) star--along with a pre-fame Philip Seymour Hoffman--the uncredited lead roles are the tornados, created with eye-dazzling computer-generated effects. SPEED director Jan de Bont takes the helm for this massive box office hit, while bestselling author Michael Crichton contributed the fast-moving story. TWISTER earned Academy-Award nominations for its achievements in sound and visual effects.
