At this point, it seems as if there will be two different movies, one from the cast we’ve seen in Star Trek, Star Trek into Darkness and Star Trek: Beyond, and a second, potentially R-rated version.
Then, there was the more specific news that Quentin Tarantino wants to direct an R-rated Star Trek movie.
Although if you ask previous Star Trek cast members, many would probably be on board to do an R-rated movie should they be wanted for the gig.
We’ve known a fourth Star Trek movie would be coming for a while, however, there was some confusion about how the project would come together.
