We learned back in November that David S. Goyer (Blade: Trinity, The Unborn) was tapped to direct Masters of the Universe for Sony, a brand new live action feature film that’ll bring He-Man and Skeletor back to the big screen. Well, things have changed.

Variety is reporting today that Sony Pictures is now on the hunt for a new director, as Goyer has exited the project. “The filmmaker and screenwriter has had to drop out because of other commitments,” the site notes. Goyer will remain on board as executive producer, and he also wrote the script that he was set to direct.

Goyer has written films such as Dark City, Blade, Batman Begins, Ghost Rider: Spirit of Vengeance, Man of Steel and Batman v Superman: Dawn of Justice.

Set on the planet Eternia, the story follows a warrior named Prince Adam who turns into the heroic He-Man and battles a villain named Skeletor out to conquer Castle Grayskull.

Sony has set Masters of the Universe to be released on December 18, 2019.

The “He-Man” franchise began as a successful toy line from Mattel and was turned into a cult hit kids’ TV series in 1983. Four years later, the series was turned into a live-action film starring Dolph Lundgren as He-Man and Frank Langella as his nemesis, Skeletor.
