It isn’t as new as some may think. I remember reading a book called Queering the Color Line by Siobhan Somerville, which looked as far back as silent film to show the overlap in race, gender, and sexual identity in its representation/misrepresentation throughout film. It is not as strange as it may seem to think about the overlaps: to see what was allowed, who was allowed to portray a person of color/a woman/a character with homosexual traits, and what was considered more taboo or more accepted than the next.
We just got a book in that isn’t quite as heavy, and a bit more focused in content. Out at the Movies: A History of Gay Cinema by Simon Callow. This book covers not only the history of homosexuality and attitudes towards it as portrayed through time, but also discusses the roles of closeted and openly gay actors, actresses, filmmakers, writers, producers, and directors. The focus of this book focuses more on modern cinema than Queering the Color Line, but that’s certainly not a bad thing. Recommended for those with a Queer Studies interest and film buffs.
