Husbands and Wives

After their friends Jack and Sally split up, the marriage between college professor Gabe and magazine editor Judy encounters several difficulties: Gabe becomes close to one of his students, aspiring writer Rain, while Judy takes it upon herself to introduces Sally to one of her colleagues, becoming dissatisfied when they start a relationship. Meanwhile, Jack and Sally's separation wildly ranges from amicable to hostile, when it's revealed both are jealous of the other having found a new love interest.

Examples of tropes:

Comedy of Remarriage: Subverted.
The Ditz: Sam, Jack's new girlfriend, a good-natured (and much younger) aerobics instructor whose main interests are health foods and fads.

Man: "If astrology were true - "

Sam: "It is true! It is totally, totally, totally provable, you know?"

Woman: "Provable how? From gypsies?"

Sam: "Well, it's totally logical, right? You know, why wouldn't the position of the planets have an influence on our personalities?"

Foreshadowing: Gabe states Jack and Sally will be back together in a year. He's right, but Gabe and Judy will break up.
Happily Married: Rain's parents are happy and content, in stark contrast to Jack, Sally, Gabe and Judy.
High Class Call Girl: Before leaving Sally and finding a girlfriend, Jack hires consummate professional "Shawn Grainger".
Ice Queen: Jack sees Sally as one, of the "bossy neurotic wife" variety; a major source of trouble throughout their marriage has been Sally's apparent frigidity, combined with her upper-class tastes.
Meaningful Name: "Rain", named after poet Rainer Maria Rilke.
Mockumentary
Reality Subtext. And HOW.
Teacher Student Romance: Everything seems to be headed that way for Gabe and Rain, but he changes his mind after kissing her at her birthday party. Doesn't make him happier in the long run, though.
Typecasting: In 1992 Juliette Lewis was better known as a precocious, provocative young woman type - Cape Fear had been released the year before.
