Classic eighties adventure series from Glen A. Larson (Battlestar Galactica, Buck Rogers in the 25th Century, The Fall Guy etc.). Although Knight Rider's run ended in 1986, the continued popularity of the series is such that a long-awaited movie is currently in production (due 2008).

Michael Knight is a lone crime fighter who was given a new lease of life (and a new identity) by the mysterious chairman of Knight Industries. His role is to fight crime, using the resources of Knight Industries (including K.I.T.T. a super-intelligent high-performance car).
