with the sexual revolution of the 60 and there of course would have to be a movie about sex . bob and carol and ted and alice be it . have visit a therapy group and bob and carol sander ( robert culp and natalie wood ) have become more open about their sexuality and and be identify more with the counterculture in general . their repressed friend and ted and alice henderson ( elliott gould and dyan cannon ) can not seem to get into it . but while in a hotel room in las vega and after they have all reveal some secret and they decide to have an orgy . you have probably see the picture of the four of them in bed together . when this movie come out and many critic think that it have a cop out end . in an interview and director paul mazursky explain that he felt that they only could go as far a they eventually go . anyway and you can not judge an entire movie by one individual scene while it what the movie say overall that matter . a for the character and bob seem sort of wooden and carol be hot ( a natalie wood always be ) and ted be a dork and and alice be a little eccentric . overall and it a pretty good movie .
