Scarlett Johansson is set to become the highest paid actress in Hollywood by raking in $25 million to star in her own Black Widow movie.

Superstar Scarlett, 33, has signed up to return as Natasha Romanoff for a one-off superhero film, expected to hit theaters in 2020.

Marvel and Disney have agreed to the $25 million deal which will make the mother-of-one Hollywood's highest paid actress for a single movie.

It is understood Scarlett's agents are also negotiating for her to get a producer's credit on the Walt Disney Pictures production.

Insiders say that should the movie - based on the comic book heroine - generate more than $900 million, the star will also get an estimated $6 million bonus check.

This means Scarlett could walk away with around $31 million, made up of wages, perks, and bonus, if the movie explodes at the box office, which given the franchise's history - is very likely.
