Paramount Pictures has now removed the Star Trek film set for release on December 22, 2023. The news first came from the trades, with Variety noting the move was “inevitable” following the news from last month of director Matt Shakman exiting the project.
After Shakman left the project, producer JJ Abrams and Paramount were reported to have started a hunt for a new director. There are no details on the current status of the project and no new statement from Paramount today. Last month following Shakman’s exit the studio did issue a statement that said (in part), Paramount was “excited about the creative vision of this next chapter and look forward to bringing it to audiences all around the world.”
