The Owl and the Pussycat (1970)

Can a bickering odd couple in Manhattan become friends and maybe more? Owlish Felix is an unpublished writer who vents his frustration by reporting to the super that the woman in a neighboring flat takes the occasional payment for sex.

She's Doris, more wildcat than pussycat, and when Felix's peeping-tom-tattle-tale routine gets her bounced from her apartment, she knocks at his door at 3 AM, aggressive and ticked off. They yell, lose another apartment, and pick up where they left off in a friend's flat and beyond. Dancing by the light of the moon seems unlikely for this owl and pussycat.
