Invincible on AllMovie

A martial-arts master who had formerly fought alongside the malevolent Shadowmen eschews the dark side in a bid to redeem himself and train a group of misfits to do battle with the ultimate evil in this high-kicking adventure from producers Mel Gibson and Jet Li. Having formerly spent his time fighting to destroy the Earth with the supernaturally charged Shadowmen, former immortal Os (Billy Zane) knows a thing or two about the Shadowmen's plan to take over the planet. If there is any hope for the human race, Os must do his best to train his students to take on Slate -- the all-powerful leader of the Shadowmen.
