Sounds like an expensive "to do" just to get your rocks off, but the funding is aided by several high fallutin' businessmen who gamble on the attraction. Still, it must have cost millions to start the entire enterprise, what with the complex itself and the fleet of soldiers and the helicopter they transport the combatants in after they're kidnapped. We're talking a level of crotch-fueled devotion that is truly once-in-a-lifetime.
Anyway, Billy and his girlfriend are kidnapped and he is forced to fight for his freedom and his newly distressed damsel. Billy's pretty slight for an action hero, despite being a football player, but luckily a sweaty dude that occasionally wears a checkered half-shirt trains Billy and turns him into a still slight but not incompetent fighting machine. That's pretty much the entire plot folks, if you care about such things.
Despite a few wonderfully ludicrous action moments, Legion of Iron is not about action really, but rather, a three-headed monster of confused fashion (a mind altering combination of gladiator wear, 80's futuristic clothes, and low rent late 80's fashion), some of the most homoerotic training sequences I've ever seen (and god knows I've seen some homoerotic training sequences), and the central performance of Erika Nann as the evil queen Diana, slipping into a garish new outfit for every scene and unleashing a catty barrage of dominatrix-isms. I think the movie is best viewed as some sort of bizarre fetish fashion show rather than an action-packed throwback to those gladiator movies of yore. In that spirit, here are a bunch of screenshots from the movie, along with three gifs at the end that spoil several of the most WTF action moments. Enjoy.
