Help with an older film/stars

I am trying to find out the name of a film from a ways back...if this plot line rings a bell with anyone. A man is the main character, white, short dark hair. He is goofy as all hell talking about world peace or something to that extent but the two women are the ones I am trying to find. One is a white thicker mature blonde with shorter hair and large breasts. The other is a white thinner woman with wavy/curly hair. They are both in scenes with men, and then in a scene together with two men. If any of you gurus know what I am referring to please drop me a line. I know this is so vague...Sorry that's all I can remember from it, but it is a much older film...
