Marvel Studios has announced Phase Three of the Marvel Cinematic Universe, which excited most Marvel fans. The rollout includes the company's first film led by a female superhero, Captain Marvel, a.k.a. Carol Danvers. Fans have been asking for a female-led movie for some time now, and they’ve only gotten louder since DC announced a "Wonder Woman" film. While Marvel fans definitely consider getting a "Captain Marvel" movie to be a win, many fans are asking another question: Why isn’t Black Widow getting a movie?

Scarlett Johansson has appeared in “Iron Man 2,” “The Avengers,” “Captain America: The Winter Soldier” and “Avengers: Age Of Ultron” as Natasha Romanoff, a.k.a. Black Widow. Many moviegoers find her character interesting, but there is never a lot of time to explore her background when she is in other people’s movies. So when Marvel President Kevin Feige announced a "Black Widow" movie in development in 2010, fans were excited to learn more about the secret agent.

“We’ve already started discussions with Scarlett about the idea of a solo movie and have begun putting together concepts, but ‘The Avengers’ comes first,” Feige said at the time.

Four years later, “The Avengers” films are still coming first. And it doesn’t look like she’ll get her own movie in the foreseeable future. Feige stated that a Black Widow movie wasn’t in the works right now.

“Frankly, it’s about bringing new characters to the screen. Black Widow couldn’t be more important as an Avenger herself,” he told Entertainment Weekly. “Her part in ‘Avengers: Age of Ultron’ is very, very big and further develops and further enhances her character. The plans we have for her throughout the rest of the ‘Avengers’ saga is very, very big. A linchpin, in fact, to those films. So instead of taking her out, instead of doing a prequel, which we haven’t done yet, we’re continuing the forward momentum and continuity of the cinematic universe of which Widow is a key, key part.”

With the announcement of “Avengers: Infinity Wars,” which will be released in two parts, this means that she’ll appear six Marvel movies as a superhero without having a film of her own. It isn’t as if Johansson can’t handle leading a sci-fi/action/adventure flick on her own. She starred in “Lucy” this summer as the titular character, and the film earned more than $400 million at the box office. It seems that Johansson thinks she is ready to step into her own Marvel film.

While promoting “Captain America: The Winter Soldier,” she stated that she would like to have a Black Widow movie. “If you want to see a Black Widow spin-off movie, then I want to see it,” she told the Guardian.

There is definitely a group of fans that want to see it as well. Black Widow fans on Tumblr have created the Black Widow Offensive, a social media campaign on Nov. 2 to let Marvel know they want the movie. The campaign asks that “everyone in support of a Black Widow movie tweets marvelentertainment using the hashtag #BlackWidowMovie demonstrating the wide fan base in favour of it.”

The initiative, promoted by a Tumblr blog called Where Is My Black Widow Movie?, clarified that this isn’t about hating the Captain Marvel movie. Having a female superhero is a great achievement, but they don’t want just one woman on screen. “We need to be vocal about how getting a Carol [Danvers] movie isn’t enough to placate us,” the blog states. “We don’t just want a token female character, we want a million of them. And we want Natasha to be one of them.”

The "Black Widow" movie campaign is hitting Twitter on Nov. 2 and the Captain Marvel movie is slated for July 2018.
