I noticed Damnation Alley on YouTube and watched it this evening. I saw it in the theater when it came out in October 1977 and saw it again when it came out on VHS. It only arrived on dvd in 2011 but I didn't buy a copy. It's a goofy adaptation of the Roger Zelazny novel about a post-apocalypse world. They changed the book and Zelazny didn't care for the movie much. I enjoyed it well enough. It's not a great movie but it's kind of fun. The story is about average and the effects of mixed quality. It's worth a look but it's not something I would need to own.
Jan-Michael Vincent and George Peppard are the main characters. The guys were Air Force men until things fell apart. They hang out at their missile silo, even after the big bang, until an accident blows the place apart. They were off site when it happened and there's only a couple of other survivors. They take off in a couple of Landmasters to seek out a radio signal from Albany New York. There was only one vehicle made for the movie at a cost of $350,000. That's it above. It's been on the car show circuit since 2005. The guy have an adventure along the way to Albany and they loose Paul Winfield to ravenous bugs. Albany proves to have survivors and it's sort of a happy ending.
