The best news about the revelation that one (only one?) of the Power Rangers may be gay has been the lack of calls to boycott the film. In the brief but much-talked-about scene, the colorful teammates of the Yellow Ranger realize that she may be having girlfriend — not boyfriend — problems. It is a quiet moment and a small step forward for the representation of diverse sexuality in superhero movies. What stands out even more is that moviegoers didn’t bat an eye, propelling the film to a surprisingly strong $40.5 million opening weekend.

For die-hard comic book fans, the current age of silver-screen heroes is a dream come true. The slate of coming films through 2020 even includes “Ant-Man and the Wasp” from Marvel Studios and “Aquaman” from DC Entertainment, starring characters who in the past would be hard to imagine having their own movies. But where are the lesbian, gay, bisexual and transgender superheroes, who have been protecting the innocent for more than two decades? For anyone craving their stories on the big screen, as I do, there are no clear signs ahead. Some characters with non-straight relationships in their back stories have made it to the movies, but those details have not yet made it out of the closet.

“Iceman, Mystique and Catwoman are L.G.B.T. in the comic books, but appear straight onscreen.” So begins a trailer for an imaginary film about a man who becomes a hero while also beginning a relationship with another man. The trailer, created by the young director Mike Buonaiuto, has its flaws, but there is something magical about its matter-of-fact handling of the lead characters.
