Written, produced and directed by Michael Carreras (Maniac (1963), Curse of the Mummy's Tomb (1964) and The Lost Continent (1968)), this Hammer adventure was made using sets recycled from One Million Years B.C. (1966), and it was shot quickly in a meagre 4 weeks, although it took nearly a year for the film to get released. But, it's more derivative and dull than One Million Years B.C. was. In Africa, English explorer David Marchant (Michael Latimer) and Colonel Hammond (Robert Raglan) are leading a safari searching for a leopard, which Marchant finds and kills, but he is soon ambushed and captured by a primitive tribe of women who are led by Queen Kari (Martine Beswick), who chooses Marchant to be her mate, but Marchant is horrified by her brutality and refuses her advances. When he's put in prison until he changes his mind, Merchant meets Saria (Edina Ronay), whose people have been oppressed by Queen Kari's regime and nastiness for years, and Marchant comes up with a plan to bring down the rule of Queen Kari. It should have been a good film, but it is quite dull and it takes it's sweet time to get going. Hammer didn't have much faith in the film, and when it was released in the UK, it was a flo, so it was cut heavily and put on as the B feature with The Devil Rides Out (1968). Plus it has some laughably unrealistic set pieces.
