I'm currently reading Roger Zelazney's The Last Defender of Camelot, a collection of short fiction. I'm reading a novella (or novelette, or whatever the name is for the length this is) called Damnation Alley. There's a little bit that introduces each piece, and this one mentions that he turned it into a novel (but he likes the short version better), which got turned into a movie. According to IMDB, it was made in 1977. It stars the guy from Airwolf and George Peppard. I remember watching Airwolf on TV, but I don't really remember anything about it, other than there was a guy who had a helicopter. I think I might have to hunt down the movie.
