We're knee-deep in summer-movie season,  and if 2013 is any indication, don't expect a lot of gay characters onscreen. This week GLAAD released its Studio Responsibility Index, gauging representations of in the seven major Hollywood studios —and didn't exactly give them two thumbs up.

Out of 102 major-studio releases from 20th century Fox, Lionsgate, Paramount, Sony Columbia. Walt Disney, Universal and Warner Bros, only 17% had LGBT characters—a small uptick from 14% in 2012,. But only 7% of them passed the “Vito Russo Test” — GLAAD’s way of measuring whether a depiction is substantial and positive.

On the other hand, Sony Columbia became the first mainstream studio to receive a “good” score thanks to films like the YA adaptation The Mortal Instruments: City of Bones and the dance drama Battle of the Year.

Though it scored only "adequate" overall, Universal received praise for the inclusion of a gay hero in Kick-Ass 2.

Comedies were more likely to be inclusive, with 8 out of 19 films including LGBT characters. In the lucrative action/sci-fi blockbuster genre, though, there were only four queer characters out of 43 films examined. Five out of 28 dramas were inclusive, while GLAAD found no LGBT characters in any animated or family-oriented films. (Guess they didn't buy that bit about Oaken in Frozen being gay.)

“These studios have the eyes and ears of millions of audience members, and should reflect the true fabric of our society rather than feed into the hatred and prejudice against LGBT people too often seen around the globe.”,” said GLAAD President Sarah Kate Ellis.
