Longtime Companion is a 1989 American romantic drama film directed by Norman René and starring Bruce Davison, Campbell Scott, Patrick Cassidy, and Mary-Louise Parker. The first wide-release theatrical film to deal with the subject of AIDS, the film takes its title from the euphemism The New York Times used during the 1980s to describe the surviving same-sex partner of someone who had died of AIDS.
