LOS ANGELES (Reuters) - The Star Wars movie franchise has dropped another director, Walt Disney announced on Tuesday. It said director and writer Colin Trevorrow would no longer be involved in the 2019 film Star Wars: Episode IX.

Disney and Lucasfilm blamed differing visions but did not name a replacement.

Trevorrow was due to write and direct the movie.

It was the second Star Wars project to lose a director this year.

Disney in June said Phil Lord and Christopher Miller had left the Han Solo Star Wars spin-off movie due to creative differences.

They were replaced by Hollywood veteran Ron Howard, Oscar-winning director of A Beautiful Mind.

Star Wars: Episode IX is part of Disney's expanding slate of Star Wars movies, rebooted by 2015's hit, Star Wars: The Force Awakens, that reunited original 1977 stars Harrison Ford, Carrie Fisher and Mark Hamill.

Disney gave no details about the reasons for Trevorrow's departure but Hollywood trade paper Variety cited sources as saying the split stemmed from differences over the script.
