A homicidal maniac, riddled with police bullets and failing on the operating table, is given an untested regenerative serum and becomes, overnight, an invulnerable superman. Chuck Norris is the Texas sheriff (he actually uses the expression "dad gum") who must deal with this unusual problem, when he isn't single-handedly destroying a biker gang à la Billy Jack. The situation recalls the curious mixture of the mundane and the fantastic that was to be found in 1930s serials, and there are some genuinely suspenseful, well-staged action sequences. But the love interest and the roly-poly, comic-relief, Andy Devine-type deputy (we're supposed to feel sad when his ribs are crushed in the superman's bearhug) make sure that the movie doesn't rise above Chuck Norris's standard. Directed by Michael Miller. (1982) — Duncan Shepherd
