One night when I was a kid, in the mid eighties, I saw a Sci-Fi movie late night on TV. I seem to remember it had a really long name. It opened with the main character on his spaceship (which was kind of a piece of junk), drunk, and talking to his lawyer over radio about his divorce from his wife.
Later, planetside, there were lots of Mad Max-esque vehicles in the desert, some of them really big and complicated. That's about all I remember!
