capture the sexual revolution of the late sixty and this comedy present two married couple and free thinking and ready ( or so they think ) for an open marriage bob ( robert culp ) and carol ( natalie wood ) and their best friend and a more traditional couple and ted ( elliot gould ) and alice ( dyan cannon ) . i love the film and i believe that it have age very well . it theme and the way it be present be definitely not date . many scene be hilarious and superbly act by all four main character and gould and cannon be outstanding . i also believe that 60 be the best dressed decade for woman ( do not like pirate shirt for men and though positive . ) and i enjoy the beauty of the film . it get real class that be timeless .
