Several nude scenes were filmed, but tend to be excluded from the U.S. version of the movie. They include: Robin Hawdon and Victoria Vetri's love-making in the cave and the scene where they both go skinny-dipping. The aforementioned nude scenes are featured in the U.K. version (as Victoria Vetri revealed in a 1984 interview).
The original 1970 UK cinema version was cut by the BBFC to edit some scenes of violence for an 'A' certificate including the fights with the snake, the pterodactyl and the man-eating plant. The film was re-released for cinema in 1980 and this print was culled from the edited U.S print, though the UK censors removed all traces of nudity. This latter version was the print released on Warner video in 1988.
