This classic piece of horror doesn't have a significant amount of overt gay content. Charlie Brewster is an over-imaginative teen with a single mom and outcast friend. When some men move in next door, his mom wonders if Bill, the new antique dealer, and his live-in carpenter, Jerry, could be gay. But the antique's dealer is really a vampire and while the vampire does seduce mostly women, there is significant homo-eroticism between him and his ghoul.
Several scenes stand out in this movie. In one, the vampire, Chris Sarandon, seduces the misfit boy, known as Evil Ed and tells him that he knows what it's like to be different and an outsider. In another, the vampire puts his arms around his ghoul, played by Jonathan Stark, as an incredible show of solidarity, .
As notes of interest - Charlie's girlfriend is played by openly lesbian actress Amanda Bearse, while his best friend Ed starred in gay porn under the name Stephen Geoffreys. His mentor, Roddy McDowell, was also known to be gay.
