The Real Problem Facing Star Trek 4
Among the many difficulties in launching Star Trek 4, the real issue plaguing the next movie is the Kelvin timeline. Star Trek 4's director, Matt Shakman, recently left the project in favor of helming Marvel Studios' Fantastic Four. This put the long-delayed new Star Trek movie in limbo. Meanwhile, it can be conjectured that another problem that has caused a lack of urgency in making Star Trek 4 is that the new Star Trek TV series on Paramount+ have made the Kelvin Timeline pointless.share
