In a recent interview with Collider, screenwriter Mark L. Smith - who worked on a script that Tarantino was in talks to direct, outlined the director's hesitation over helming a fourth instalment of the re-booted Star Trek franchise. "Quentin and I went back and forth, he was gonna do some stuff on it, and then he started worrying about the number, his kind of unofficial number of films," The Pulp Fiction director has been open about retiring from directing after completing ten films, with The Movie Critic set to be his last.
