Director Colin Trevorrow has stepped down from Star Wars: Episode IX, Lucasfilm has confirmed.

The studio made the announcement this afternoon, confirming Trevorrow and executives made the mutual decision to part ways. Trevorrow signed on to direct the movie back in 2015.

“Colin has been a wonderful collaborator throughout the development process but we have all come to the conclusion that our visions for the project differ,” the statement reads. “We wish Colin the best and will be sharing more information about the film soon.”

The announcement about Trevorrow comes just months after Lucasfilm confirmed that Phil Lord and Christopher Miller had parted ways with the studio over the untitled Han Solo movie. Ron Howard was brought in to finish the movie instead.

This marks the third time a director (or directing team) previously attached to a new Star Wars film has left their project. Director Josh Trank was originally attached to direct an untitled Star Wars spinoff movie, but was removed from the project in 2015.

Star Wars: Episode IX is slated to be released on May 24, 2019. It’s unclear if this decision will affect the release date.

The next Star Wars movie, Star Wars: The Last Jedi, will be released on Dec. 15.
