This chapter introduces the Swedish vampire film, Låt den rätte komma (Let the Right One In), which not only stands out from contemporary vampire films, but ranks among the very best vampire movies of the past century. The chapter mentions director Tomas Alfredson and screenwriter John Ajvide Lindqvist, who adapted Låt den rätte komma from his own novel of the same name. It also mentions a song by the lugubrious British rock singer-songwriter Morrissey as Lindqvist's inspiration for the title of his novel 'Let the Right One Slip In'. It recounts Let the Right One In's world premiere on 26 January 2008 at the Göteborg International Film Festival in Sweden and screening at other festivals in Europe, North America, Australia and South Korea. The chapter explains why Let the Right One In stands head and shoulders above other recent horror movies like Twilight from 2008.
