Billed as Hammers "100th Production" (it wasn't) and fueled by the double shot of Raquel Welch in her fur bikini and Ray Harryhausen's stop motion prehistoric beasts, it arrived on a wave of publicity in 1966 and was both Hammer's most expensive (£422,000) and the highest grossing production as it raked up $8,000,000 in the U.S. alone. Directed by Don Chaffey (JASON AND THE ARGONAUTS), it was shot on location in the Canary Islands (with interior stuff at Elstree) and has a wide open spacious look to it unlike the set bound Gothic horrors that Hammer was known for. Producer (and writer) Michael Carreras smartly hired both a director and cinematographer (Wilke Cooper) who had both worked with Harryhausen before.
Originally clocking in at 100 minutes Fox cut it down to 91 minute for U.S. release losing some blood, violence, hints of cannibalism along with a bit of wild cave woman dancing by Martine Beswick (most likely it was also probably cut a bit for better double feature compatibility). In a really bizarre move Fox edited some of Harryhausen's stop-motion animation work including bits of the Allosaurus attack which is one of his greatest creations.
Kino Lorber's spectacular new blu ray shares the same 4k restoration that Studio Canel released last year of the longer British cut while adding a second disc with the same restoration of the 91 minute U.S. version. Extras include interviews with Martine and Raquel (who at 75 looks like she could still climb into that fur bikini with no problem), a vintage interview with Ray Harryhausen, still gallery & trailers and a full length fact packed commentary by Tim Lucas on the long cut.

No better way to watch a Hammer dbl. feature then if your "scientifically cool" !
