April in Paris

1970 The Owl and the Pussycat began life as a two-character Broadway play by Bill Manhoff, about a stuffy author who entered into an explosive relationship with his neighbor, a foulmouthed, freewheeling prostitute. George Segal portrays the male lead.  Beyond the added characters (including Robert Klein as Segal’s swinging roommate), the heart and soul of the film is the Segal-Streisand relationship; he is utterly appalled by her lifestyle, she is turned off by his prudishness, and both are made for each other. I suppose opposites attract.
