About Last Night... (1986)

Continuity mistake: When Danny & Debbie are having their New Year's dinner at home, the champagne foam instantly disappears in the very next camera angle after pouring it.

Danny: Hey, know one thing - I never screwed around on you.
Debbie: Oh, well, let's just give the boy a medal! I didn't realise it was such a sacrifice.

Trivia: The original title of this film was 'Sexual Perversity in Chicago' (taken rom the play it is based on). The title was changed after many newspapers and TV stations refused to run ads for a film with such a title.
