Diamond Frontier

Characterized by some critics as a "South African western", Diamond Frontier stars Victor McLaglen as ruthless diamond hunter Regan. The villain's reign of terror as he searches for the precious gems is checked by Charles Clayton (John Loder), freshly escaped from a brutal penal colony. A wild escape through the jungle enables Universal Pictures to exercise its usual prerogative of lifting great chunks of celluloid from its stock-footage library. (allrovi.com)
