Six months after teaming up with Warner Bros. to helm their upcoming live-action film Wonder Woman, MacLaren has left the project.

Update (April 13, 2015): MacLaren has left Wonder Woman due to creative differences, according to Warner Bros. “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. The news is very disappointing, as many were looking forward to seeing a female director of MacLaren’s stature take on a female-driven super hero film.

Original story (November 24, 2014): The Hollywood Reporter says that MacLaren was one of the frontrunners to direct Wonder Woman, starring Gal Gadot, in the summer before the studio expanded their search in the fall.

WB was hoping to find a female director for obvious reasons, but there was some uncertainty because a woman hasn’t directed a project of this magnitude before, according to THR.

MacLaren will work with the film’s yet-to-be-revealed writers on a script. Wonder Woman is being produced by Charles Roven, Zack Snyder and Deborah Snyder.

The director is best known for having executive produced The X-Files and Breaking Bad. She’s directed several episodes of the latter, Game of Thrones, and The Walking Dead.

Wonder Woman will be the first female-led, female-directed superhero film in modern times from one of the major studios. You’ll first see her in Batman v Superman: Dawn of Justice, along with several other Justice League characters who are slated to receive standalone films between now and 2020.

While DC is first out of the gate with their female superhero film, Marvel recently announced plans for a Captain Marvel movie, which is slated to hit theaters July 6, 2018.

Wonder Woman opens June 23, 2017.
