'Wonder Woman' will not be the first major female superhero movie directed by a woman. Michelle MacLaren has dropped out of the project over "creative differences," according to The Hollywood Reporter.

"Given creative differences, Warner Bros. and Michelle MacLaren have decided not to move forward with plans to develop and direct Wonder Woman together," the studio said in a statement.

Those "creative differences" could mean anything, but it brings to mind the similar departure of Patty Jenkins from "Thor 2." Jenkins, too, would've been the first woman to direct a Marvel superhero movie.

MacLaren's hiring was an exciting move for fans, as the veteran director had overseen many thrilling episodes of "Breaking Bad," "Game of Thrones," and "Walking Dead," but had yet to helm a feature film.

It's unclear if her departure will push back the release date for "Wonder Woman," currently set for 2017.
