Creatures the World Forgot

Creatures the World Forgot is a 1971 adventure film directed by Don Chaffey and produced and written for Hammer Films by Michael Carreras. The film concentrates on the daily struggle to survive of a tribe of Stone Age men. Very little dialogue is spoken throughout the film, apart from a few grunts and gestures.

Years later, the now adolescent twins, dark haired Rool and fair haired Toomak fight for their fathers attention. Rool tries to rape the mute girl. She escapes but falls into the grasp of a marauding tribe. Toomak leads Mak and the other tribesmen to the marauders cave. A battle ensues and the marauders chief is killed by Toomak. Toomak rescues the mute girl and takes the defeated chiefs daughter, Nala, as his wife. Mak names Toonak as his successor as tribal chief and then dies of wounds sustained in the battle. Rool disputes the decision and he fights with Toomak in a ritualised battle. On the brink of victory, Toomak spares his brothers life. Toomak decides to leave, taking Nala and half the tribe with him. Consumed with hatred for his brother, Rool decides to track Toomak down. Rool and his men are attacked by a forest tribe, but are rescued by Toomak. Rool, still hating his brother, abducts Nala. Toomak chases after Rool. At the top of a cliff, Rool stakes Nala to a pyre. Toomak and Rool fight whilst Nala frees herself only to be caught in the grasp of a python. Toomak saves Nala whilst the mute girl stabs an effigy of Rool, sending him falling to his death.All of the exterior sequences were shot in Namibia and South Africa. The film is the fourth and last of Hammers Cave Girl sequence of films, preceded by One Million Years B.C. 1966 also directed by Don Chaffey, Slave Girls 1967 and When Dinosaurs Ruled the Earth 1970. Like the other films it trades heavily on the audience appeal of scantily clad tribeswomen. This film eschews the stopmotion dinosaurs of the first and third of the series. ........
