Director Colin Trevorrow has pulled out of the Star Wars: Episode IX due to differing "visions" with Lucasfilm.
Lucasfilm will now need to find a new director for the film, which is due to be released in May 2019, the BBC reports.
A statement released on the Star Wars website read: "Lucasfilm and Colin Trevorrow have mutually chosen to part ways on Star Wars: Episode IX.
"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. We wish Colin the best and will be sharing more information about the film soon."
It is not yet clear who will replace Trevorrow but according to Deadline Rian Johnson is thought to be a strong contender. He is currently directing The Last Jedi which is set to be released in December.
Some reports also suggest it could be JJ Abrams, the director of the 2015 Star Wars film The Force Awakens.
The director's departure comes less than three months since the directors for a Han Solo spin off film also left.
Phil Lord and Christopher Miller have now been replaced with Ron Howard.
