Apartment Zero, also known as Conviviendo con la muerte (Spanish: Living with Death), is a 1988 British-Argentine psychological-political thriller film directed by Argentine-born screenwriter Martin Donovan, co-written by Donovan and David Koepp and starring Hart Bochner and Colin Firth. It was produced in 1988 and premiered at film festivals throughout the next year. The story is set in a rundown area of Buenos Aires at the dawn of the 1980s, where Adrian LeDuc becomes friends with Jack Carney, an American expatriate who rents a room from him. Gradually, Adrian begins to suspect that the outwardly likeable Jack is responsible for a series of political assassinations that are rocking the city.

Famously suffused with homoerotic overtones and moments of black comedy, it received mixed-to-positive reviews at the time of its release, and currently has a Rotten Tomatoes' score of 75% positive reactions from both critics and viewers.
