The Seven Magnificent Gladiators (1983)

If you're as old as I am, then there's a chance you'll have spotted something on the ridiculous cover art that lets you know exactly what you're in for (besides Lou Ferrigno cosplaying the lovechild of Hercules and Conan the Barbarian). Situated in the corner is the telltale hexagonal logo of the Cannon Group. Yes, we're in Cannon territory, folks, so adjust your expectations accordingly.
Like the title implies, it's a ripoff of Seven Samurai (1954) and The Magnificent Seven (1960) but in a gladiatorial era. The leather-fetish-clad figure pictured third in the orderly queue on the cover is the antagonist that Ferrigno and his posse must vanquish, a half-god son of a sorceress.
It's a good-natured romp with scenes stitched haphazardly together and dubbing that's bad but not as atrocious as I'd feared it would be.
