But when is it out? And what is it about? Here's what you need to know..
When is Captain Marvel out?
The twenty-first film in the epic Marvel Cinematic Universe will be released in the UK on March 8, 2019.
In June 2018 Marvel revealed they are still a "few months away" from releasing a trailer on the future star of the Avengers.
In an interview with Entertainment Weekly, Brie Larson said, "She can't help but be herself. She can be aggressive, and she can have a temper, and she can be a little invasive and in your face.
"She is also quick to jump to things, which makes her amazing in battle because she's the first one out there and doesn't always wait for orders.
But the [not] waiting for orders is, to some, a character flaw."

Brie Larson as Carol Danvers/Captain Marvel

What is the plot for Captain Marvel?
The film is a prequel to the 2018 film Infinity War.
Captain Marvel is set in the 90s which places it before Iron Man, which was released in 2008 and was the first movie in the Marvel Cinematic Universe.
It showcases former US Air Force pilot Carol Danvers (Brie Larson) who gained superpowers when her DNA became fused with an alien's during an accident.
However, the film will NOT be an origin story for the character as the movie will begin with Carol already in possession of her cosmic powers.
After joining Starforce, an elite Kree military team, Carol returns to Earth only to find herself caught centre of an intergalactic conflict between two alien worlds.
It will also feature a younger two-eyed Nick Fury and his first interactions with superheroes that led to him gaining the pager that contacts Captain Marvel at the end of Infinity War.
