In the early 1940s, films started to appear where homosexual characters were represented as inherently criminal. These early representations were often subtle or implicit because various production codes operating in the United States and United Kingdom forbade explicit depictions or naming of homosexuality. During the 1940s, homosexuality was associated with disease and sexual deviance. This ensured that these early depictions were unflattering. Gradually, as time progressed and homosexuality became a less taboo topic, representations of homosexual criminality became less coded and more explicit. Filmmakers became bolder in their treatment of the theme of homosexuality and crime. The most fascinating discovery is that, when it comes to popular culture and the cinema, murder is the crime that is typically associated with homosexuality. However, murder has been a mainstay of crime film plots and so it is not surprising that homicide features in films linked to crime and homosexuality. By the year 2000, it is apparent that the cinematic treatment of homosexuality and crime had evolved to become quite sophisticated. Whereas earlier films reviled their homosexual characters such that they attracted little empathy from the audience, these later films have sought to engender a greater tolerance and sympathy for the homosexual killers they depict. Finally, it is important to note that films that depict homosexuals as killers are not an expression of homophobic sentient per se. Crime films have long situated killing as an essential aspect of their plots, and so films that feature homosexuals as murderers are simply a subset of this most popular cinematic genre.
