That makes sense. The news about Quentin Tarantino pitching a Star Trek movie idea came around the same time as he was starting to put together Once Upon a Time in Hollywood, which included moving the film from The Weinstein Company to Sony Pictures. In the year and a half (give or take) since then, Tarantino has shot Once Upon a Time in Hollywood and is currently on the “mix-stage” of his latest movie, as he also mentioned in his interview with Slashfilm.
