There is evidence that more female superhero movies are on the way.
"With ['Ant-Man and the Wasp'] and now with 'Captain Marvel' and many movies to be announced in the near future, I'm anxious for the time where it's not a novelty that there is a female-led superhero movie but it is a norm," Feige told Entertainment Weekly.
Evangeline Lilly starred as The Wasp alongside Paul Rudd in the latest Ant-Man movie, and while she shared star-billing, some considered that to be the first female-lead in Marvel history.
Bible pointed to rumors about a "Black Panther" spinoff featuring the powerful women warriors of Wakanda, the fictional nation where "Black Panther" is set. Scarlett Johansson has been in six Marvel movies as Black Widow, but she has never played the lead. There has been talk of a "Black Widow" movie, but it hasn't happened yet, Bible said.
On Friday, Marvel Studios announced that it had hired Chloé Zhao, director of indie cowboy film hit "The Rider" to direct "The Eternals" for Marvel, based on a comic book about superpower near-god beings The Celestials and their villainous adversaries, the Deviants, in a war set millions of years ago. DC also recently signed Cathy Yan to direct a superhero movie based on the comic "Birds of Prey," which features multiple female leads and will star Margot Robbie, reprising an anti-heroine role she initiated in "Suicide Squad." And DC is in talks to produce a "Supergirl" film.
"Realistically, there is still a segment of culture represented by vocal dissenters," Robbins said. "The latter kind of thought is fading with each generation, though, and frankly, not nearly as strong as the demand for good movies starring characters of all genders, colors and backgrounds."
