I had never heard of this movie before tonight but just sat down and watched it in my hotel room. If you like propper sports cars from the early '70's, watch this, you'll love it! It follows the Alfa and Ferrari teams as they chase the manufacturer's championship (1972 I believe) and is narrated by Mario with several other notable drivers... The cars, the outfits they wore, and the shots of the circuits makes this one a keeper.
