Hal B. Wallis production for Paramount, reuniting Paul Henreid, Claude Rains and Peter Lorre from the supporting cast of Wallis' "Casablanca" in 1942, involves Burt Lancaster as an American hunting guide in South West Africa refusing to reveal the location of a cache of diamonds in a restricted area known as the Rope of Sand. Security chief Henreid is the hissable nasty who threatens Lancaster, Rains is the owner of the diamond company who hopes a French woman can seduce Burt into revealing all, while Lorre is a scroungy merchant who knows everyone's business. Limp action-drama with funereal pacing, an annoying femme fatale (Corinne Calvet, a Wallis discovery, in her first major role) and a sour leading man in unhappy spirits. ** from ****
