Cut version had Joan Crawford and Bettie Davis?
Yes as a giggle the two stars agreed to play in a fight scene as opposite
cave women. (Shell and Rock)who get in a big cat fight, hair pulling etc and they try to shove torches in each others faces (in a blooper Davis's wig catches fire and has to be be stomped out)
In the end the two stars could not agree on the monkey cave scene and their
footage cut except on Hammer blooper film reel)
