'American Nitro' is back!

"Seventies drag-race mayhem is back!" bills "American Nitro," a schlocky drive-in exploitation film whose only quote of praise, from a dog-eared period issue of "Car Craft," reads, simply, "SPECTACULAR CRASHES!" Director Bill Kimberlin says that he made "American Nitro" in 1979 as a response to Tom Wolfe's influential 1965 essay, "The Kandy-Kolored Tangerine-Flake Streamline Baby." "I was just getting out of high school in a small town in Northern California when Wolfe's book came out," he said. "Nitro came about as my response to the car culture I was exposed to in the small valley town of Boonville, Calif. Instead of 'American Graffiti,' I made 'American Nitro.'" A fitting comparison, in fact, considering Kimberlin later worked for George Lucas at ILM, starting with" Return of the Jedi." Now the movie is being released on DVD for the first time -- beware of bootlegs, warns the website -- and digitally remastered, while retaining the explosive charm and goofy narration of the 1979 original.

All of that green doesn't come inexpensive--or easy.
