From what’s been reported so far, it sounds like Tarantino’s Star Trek movie stands a good chance of moving forward, although Pegg previously expressed doubt that Tarantino would actually direct this movie given how busy the man is currently with Once Upon a Time in Hollywood.
So if Quentin Tarantino hadn’t approached the folks at Paramount and Bad Robot with his idea for a Star Trek movie, then the companies would have just moved ahead with Star Trek 4 on its own and not worried about working on another cinematic project for a while.
But evidently whatever Tarantino pitched was intriguing enough that it warranted further exploration, as The Revenant writer Mark L. Smith will pen the screenplay.
