Quentin Tarantino's pitch for a Star Trek film was fast-tracked to a writer's room in December of last year, where The Revenant screenwriter Mark L. Smith was tapped to pen the script. However, while the Kelvin Timeline's cast is still going strong, with Star Trek 4 heading towards production, Simon Pegg is unsure the cast will appear in Tarantino's film.

In an interview with The Edmonton Journal, while promoting Mission: Impossible - Fallout, Pegg revealed that Tarantino's Star Trek film likely won't happen until after Star Trek 4 is released. "Quentin's idea is another thing,” he said. "He came in to (Abrams' production company) Bad Robot and pitched it and it's been put in the bank. I think he had us in mind when he came up with the idea; he likes the new cast. But he's going to be so busy with Once Upon a Time in Hollywood that I can't see him doing it for five or six years, by which time we might be too old anyway."

Paramount announced in April that two more Star Trek films were being planned, though the film studio did not specify whether Tarantino's pitch was one of them. Details about Tarantino's Star Trek film have remained relatively scarce, with the Kelvin Timeline's cast largely being kept in the dark about the project. Spock actor Zachary Quinto stated in another recent interview that "My assumption is that it is with us. That is how it has been presented." Pegg, on the other hand, appears to be less sure.

Early reports suggested that Tarantino's Star Trek film will be R-Rated. However, Pegg has cast some doubt on that.

The Kelvin Timeline's cast will next appear in Star Trek 4, to be directed by S.J. Clarkson. No release date has been announced.
