This film was shot in only four weeks using the sets and costumes from the film One Million Years B.C. (1966) in order to offset the earlier film's cost of 140,000 pounds.
This film was originally going to be the top half of a double feature with the film The Old Dark House (1963), but after the studio head, Sir James Carreras, decided that it was not up to Hammer's high standards, it was edited down from its original 91 minutes to 74 minutes and released instead as the bottom half of a double feature with another film, The Devil Rides Out (1968).
The film's UK title was originally going to be "Slave Girls of the White Rhino", but it was shortened to "Slave Girls".
The film's U.S. title was "Prehistoric Women".
Martine Beswick said in a 1998 interview that she thought that this film was the "worst piece of rubbish," but she also admitted that she had such a fun time being in it and just breezed right through it.
