Quinto, who has portrayed Spock in the last three Star Trek movies, was asked about his involvement with Tarantino’s Star Trek movie on the Happy Sad Confused podcast.
After that, the next movie on Tarantino’s schedule could be Star Trek with the current cast.
Obviously, nothing is set in stone until the ink is dry on the contract, so Quinto wasn’t able to speak with any certainty that he would be in Tarantino’s Star Trek.
According to Quinto, Tarantino’s idea is still in the early stages of being turned into a script, and in the meantime, he will be filming his 1960s ensemble movie, Once Upon A Time In Hollywood, which features Charles Manson and a deep exploration of 1960s Los Angeles.
