Man and Superman (1979)
This romantic comedy tells the story of two rivals: John Tanner (a wealthy, politically-minded intellectual who values his freedom) and Ann Whitefield (a charming, scheming hypocritical young woman who wants Tanner as a husband). Once Tanner realizes that Miss Whitefield is hunting for a spouse (and that he is the only target), he attempts to flee from her, only to find out that his attraction to Ann is too overwhelming to escape.
