Husbands and Wives (1992)

The announcement that Jack (Sydney Pollack) and Sally (Judy Davis), two of their best friends, are separating, sparks off a crisis between Gabe (Woody Allen) and his wife, Judy (Mia Farrow) similarly gradually realising that their marriage isn’t precisely at its best moment. While Jack and Sally try to rebuild their lives with other people, Gabe starts flirting with one of his university students (Juliette Lewis) and Judy feels attracted to Sally’s new friend (Liam Neeson).
