Saw movie back in late 1980's on TV cable channel known as USA movies. Parts that I remember were situated during prehistoric times with three male role characters being told how to think also being instructed to the basis of civilization i.e. the need of monetary system strong work ethic etc. the three characters were of average appearance, one who strongly resembled sam jaffee of ben casey fame. This instruction and explanation of rules and laws of newly forming society was being given by a fourth much more physically strong and handsome male role character. In nutshell all instruction given three average characters was bias to the favor of leading man or stronger character. Movie's theme was parody to all human civilization. For some reason did not view complete movie but was so impressed at time of partial viewing have remembered for all these years and would at last like to view complete film. Thank you for any help given

I think that's "the prometheus and bob"
