I feel like the movies that are the most fun to riff are the ones you actually kinda like, and Steel Frontier is one of my favorite low-budget movies. It’s a post-apocalyptic Mad Max clone starring Joe Lara as a drifter who “helps” the recently-enslaved populace of a rubber-burning trash town fight off a raider army led by Brion James.
Don’t get me wrong, it’s NOT a great movie. You can see the wires during some of the stunts, the bad guys consistently can’t hit anything with automatic rifles from entire feet away and a lot of the performances are...uh...
But for all that, it’s got a certain degree of charm, with a plot that’s actually pretty coherent.
Also, Joe rides a super motorcycle that brings back fond memories of Megaweapon, and at one point he beats up some desert mutants and then sits down next to their corpses to finish eating a rat like nothing ever happened.
If I need anything else to seal the deal, I’m pretty sure the inspiration for Yuma’s look was “what if a buff hippy Jesus was actually a postapocalyptic cowboy biker?”
