The most contemporary cult film on this list, Let the Right One In, a Swedish picture directed by Tomas Alfredson, is the story of Oskar, a weak, bullied twelve-year-old boy who finds love and eventually revenge through Eli, a vampire girl who befriends and protects him. Ultimately a dark, malicious love story, the film currents on the power of voyeurism, anxiety, confusion and some genuine, frightening horror. Its also blanched of colour, so that even blood comes up black, the cold palette adding to the sense of cool, arctic fear that runs throughout the picture. Heralded on release as a welcome antithesis to a vampire genre stripped of its power by the likes of Twilight and its ilk, Let The Right One In was an instant cult classic, it's influence felt almost immediately. Just two years after, there was a Hollywood remake - Matt Reeves' Let Me In - but it's the original's impact which has had the biggest effect, with similar small films borrowing from it in order to try and replicate its cult popularity (think It Follows - another film which seemed to acquire cult status overnight - which borrows the its swimming pool climax straight from Let the Right One In.)
