If you feel the need for speed, racing legend Mario Andretti and his son Michael lay a patch in this revved-up IMAX feature that serves as a mini-history of auto racing with a decided accent on the father-son dynasty. Newsreel footage of spectacular crackups is interwoven with scenes of Michael's state-of-the-art racer being built and the restoration of a 1964 roadster Mario once raced at Indianapolis.
