“Avengers: Age of Ultron” comes out May 1, so naturally, the cast is making their way through a slog of interminable press days — with varying degrees of success. (Just yesterday, Robert Downey Jr. made news after walking out on an interviewer who kept asking him about his checkered past.)

But an interview that surfaced today provided a different type of fodder for fans of the successful franchise.

Chris Evans and Jeremy Renner (Captain America and Hawkeye, respectively) were asked about Black Widow’s romantic past.

“I know a lot of fans were actually pretty invested in the idea of Natasha with actually either/or, or both of you guys, and now obviously she’s with Bruce [the Hulk],” the Digital Spy interviewer said. “What do you guys make of that?

“She’s a slut,” Renner deadpanned.

Chris Evans immediately cracks up before noting: “I was gonna say something along that line. ‘She’s a complete whore.’ ”

Now, let’s get something straight here: They were obviously joking. They are obviously burnt out. It was only a matter of time before their canned apologies were released. (Evans said the duo had answered a simple question in a “juvenile and offensive way that rightfully angered some fans,” while Renner called the joke “tasteless,” but also seemed to put the onus on the endless publicity, noting that the two were “just poking fun during an exhausting and tedious press tour.”)

But in one quick snippet of their boredom and frivolity, the two said a world about the still-stagnant state of females in comic book movies in one very short exchange.

Calling the one main female character in the “Avengers” films by a derogatory name opens up a can of worms. Of course Black Widow/Natasha is sexualized; she is the (only) (voluptuous) woman surrounded by a cast of straight men. But she’s an integral part of the group, and one could argue — especially in the first movie — that she plays a larger role in the dynamics and action than a male character like Hawkeye, who at first effectively functioned as a brainwashed villain that only she could help.

So why isn’t Scarlett Johansson’s Black Widow on the official “Age of Ultron” T-shirt, posing with some of the other members of the gang? As Vanity Fair noted in an article this week, of the 60 or so pieces of merchandise currently on sale for the multibillion-dollar-grossing films, Natasha’s black-clad alter-ego is featured on exactly four.

Putting aside the fact that nearly every piece of “Avengers” swag on the official Marvel store specifies that many of the costumes/pajamas/hoodies/T-shirts are “for boys” — because young kids’ bodies are so different as pre-teens and what girls like to play dress-up? — Marvel seems to be perpetuating the idea that female superheroes just don’t sell by … not selling them? (For what it’s worth, the reusable tote, keychains and luggage seem to be gender neutral.)

And the problem isn’t limited to Marvel. Last week’s debut of the “Batman v Superman: Dawn of Justice” trailer excited DC Comics fans dying for a look at the highly anticipated film. But who are we still waiting to see? Gal Gadot’s Wonder Woman, of course. In a promo consisting almost entirely of cowls and uniforms, even just a slight glimpse at a star-spangled outfit or gold-rimmed head would not have been out of place, and would have likely been welcomed by the masses.

Despite fumbles like these, we can all agree that the superhero films have made great strides in recent years. There are less Mary Jane Watsons standing conspicuously braless in the rain, and there may even be a female director at the helm of the “Wonder Woman” spinoff.

But we’re not done fighting for onscreen equality yet, and we won’t be if tossed-aside comments about singularly important characters are the norm. Give Black Widow a break. She’s got the weight of the comic book universe on her shoulders.

Correction: An earlier version of this article said that Hawkeye was featured on the official “Avengers: Age of Ultron” shirt. He is not.
