As Time Goes By (1992)

Judi Dench and Geoffrey Palmer play Jean and Lionel, a nurse and a young soldier madly in love until he is sent away, who meet again 38 years later. Bob Larbey's scripts are quiet and grown-up, built on dry exchanges rather than set pieces. Few sitcoms of the decade were about romance later in life, and fewer still had two actors this good underplaying it. Choose it for the chemistry and the gentle wit, not for big laughs.
