This is screening as part of the BFI's Flare LGBT season.
Here is the BFI introduction: When certified horror buff Charlie Brewster becomes convinced the two guys next door are vampires, everyone around him thinks he’s just watched too many spooky movies. But as the signs add up, Charlie enlists the help of horror host Peter Vincent to destroy the suburban bloodsuckers. Essentially posing as a bourgeois homosexual couple, these snooty vamps have as much an appetite for fashion and antiques as they do virginal flesh. Meanwhile Charlie becomes so obsessed with the sexy stranger next door, his poor girlfriend doesn’t even get a look in. Fright Night is as gay off-screen as it is on: star Amanda Bearse came out in the 90s, while some might recognise Evil Ed (Stephen Geoffreys) from his later career in such, erm, classics as Uncut Glory and Guys Who Crave Big Cocks. Oh, and then there’s also Roddy McDowall...
Time Out review:Charley (William Ragsdale) has seen a coffin being carried into the house next door and a corpse being dragged out, but no one will take him seriously. In desperation he enlists a TV vampire killer, who's initially charmed by neighbour-from-hell Jerry (Chris Sarandon), before noticing the absence of his reflection in a mirror. A farrago of cartoonish exaggeration (mouthfuls of fangs, razor-sharp talons and eyes like burning coals), knowing humour and '80s camp, it shouldn't even begin to work, and yet, strangely, it does, sort of, thanks to the assured handling of writer/director Holland, and two performances in particular - Geoffreys as Charley's pal Evil, and McDowall as the timid vampire killer. The music helps, covering an ambitious range from piano-murdering suspense-raisers, through disco fodder, to a Sparks tune, 'Armies of the Night', by Ron and Russell Mael.
Here (and above) is the trailer.
