In an blog post on StarWars.com, the site has confirmed that Colin Trevorrow is no longer working on the film. Though they say the split was a mutual parting of ways, I have to wonder what really happened. Trevorrow is the 3rd director to have left or been removed from a Star Wars film since the series relaunched with Star Wars: The Force Awakens. Josh Trank was set to direct the Boba Fett stand-alone film before parting ways after the dismal performance of his Fantastic Four reboot and most recently Phil Lord and Chris Miller were removed and replaced with Ron Howard on the Han Solo film. Trevorrow most recently directed The Book of Henry.
Here is the complete post from StarWars.com:
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.
