Spacehunter: Adventures in the Forbidden Zone is a 1983 science fiction/comedy film starring Peter Strauss, Molly Ringwald, Ernie Hudson and Michael Ironside. I found it tedious.
Crackle has it online, but it can't be embedded. Youtube has it online in 9 parts, which should autoplay from here:
Moria gives it 2 stars and says, "At the very least, one can complement the film for the enthusiastic naiveté of its pulp spirit." The New York Times says, "it will probably remind you of at least a dozen other pirate, gladiator, horror and science-fiction stories, because its own plot is none too distinctive and is seriously overcrowded." The Spinning Image describes it as "Han Solo starring in Mad Max."
