Apartment Zero (1988), starring Hart Bochner and Colin Firth, with Dora Bryan, Liz Smith, and Fabrizio Bentivoglio.
Stylish thriller, set in modern day Buenos Aires, that centres around the relationship between Adrian LeDuc (Firth) and his lodger Jack Carney (Bochner). Adrian, a repressed and unbalanced loner, becomes emotionally dependent on the beguiling Jack, who in turn is a (hot, which is key) mercenary sociopath.
Jack, there is only one rule here and that is avoid the neighbours... They have been trying to find a way into me like dirty little worms...Not because they care, not because they like me, it's just to satisfy their morbid pointless curiosity...
