A personal feud between a prisoner (Sylvester Stallone) and a vengeful warden (Donald Sutherland) forms the core of this simpleminded, sub-Neanderthal, bone-crushing 1989 action drama, directed by John Flynn from a script by Richard Smith, Jeb Stuart, and Henry Rosenbaum. It would be excessive to claim that the two leads play characters in any ordinary sense; Sutherland is simply Evil, while Stallone, as usual, is the Indomitable Human Spirit. For torture and violence freaks, every clank and thud is duly and hyperbolically registered. With John Amos, Darlanne Fluegel, Frank McRae, and Sonny Landham. 106 min. (JR)
