Strangers On A Train - A brilliantly photographed murder sequence.
Not necessarily a gay movie per se, but I highly recommend Alfred Hitchcock's
Strangers On A Train (1951), for its undercurrent of homoeroticism which lends an interesting dynamic to the relationship between the two main characters: "A psychotic socialite confronts a pro tennis star with a theory on how two complete strangers can get away with murder" (IMDb).
Swoon (1992) is a decidedly gay take on the fascinating real life 1920s murderers Nathan Leopold & Richard Loeb, who were genius level university students and part of the wealthiest social elite of Chicago, and "...cold bloodedly planned the perfect murder of a child for the thrill of getting away with it."
La Cage aux Folles (1978) is a side splitting French comedy about two aging queens who are partners, one the owner of a nightclub, the other a flambuoyant transvestite who performs at the nightclub. The owner's son from a previous marriage announces his engagement and now the two old queens must do all they can to hide their lifestyle from the son's fiancee's parents, who are severely pious Catholics, when they arrive as dinner guests. This movie was remade as
The Birdcage (1996, Robin Williams, Nathan Lane), a much lesser, much less funny, Hollywood-dized version.
