Dana Brown (the son of pioneer surfing documentarian Bruce Brown) is not a filmmaker so much as a booster-club president with a camera. In his latest exercise in hero worship, Brown the Younger is completely and hopelessly enamored of the outlaw masochists of motorsport, the off-road desert racers who contest the harrowing Baja 1000 every November in Mexico. For Brown, who narrates these 94 minutes in overheated-sophomore style, the film "isn't about a race . . . it's about the human race." Any driver who isn't "legendary" or "mythical" is "a force of nature." Meanwhile, it hasn't occurred to Brown that a parade of 400 or so vehicles, each jolting past the camera in its own cloud of dirt, can get a bit repetitious. The Baja, former Indy 500 champ Parnelli Jones tells us, is "a 24-hour plane crash." Unless you're among the fuel-injected faithful, this starstruck doc may give you the feeling you've sat through all 24. Featuring Jimmy Vasser, Mario Andretti, and Robby Gordon.
