Pretty interesting article that talks about the decline of movies like the Birdcage: http://www.avclub.com/article/after-birdcage-hollywood-shoved-gay-comedies-back--234273

In 2013, news broke that Channing Tatum and John Milhiser (formerly of Saturday Night Live) were set to star in a gay romantic comedy from director Paul Feig, who was fresh off the massive success of Bridesmaids. The premise sounded endearing enough: A relative average Joey (Milhiser) lands a hunky hottie, played by the former Sexiest Man Alive himself, and cant believe his good fortune. In the time-honored tradition of romantic comedies, hijinks ensue.
If youre wondering why you havent heard of that movie, its because it never existed: Feig pitched executives the idea of the 21 Jump Street actor playing the lead, and his pie-in-the-sky choice trickled its way onto the internet as a genuine casting announcement. Nearly three years later, that film hasnt been made with Tatum, Milhiser, or anyone else. In fact, there hasnt been a gay studio comedy at all since Sacha Baron Cohen released Brüno in 2009, based on the flamboyant Austrian reporter Cohen originated on Da Ali G Show.
Todays Hollywood has gone back in the closet, and its not just Rupert Everett urging gay actors not to come out. A 2014 Williams Institute report attested to widespread bias against LGBT actors behind the scenes. The think tank polled queer SAG members and found that nearly half strongly believed that producers and studio executives think [gay] performers are less marketable. A majority personally witnessed discrimination. An openly gay extra was fired because the lead character felt uncomfortable having him around, the Institute reports. In fact, two were fired a week apart for the same reason. If the industry is uncomfortable with gay people even being on set, its no wonder theyre treated as worthless and laughable on screen.
