Quentin Tarantino has long talked about retiring after making his 10th film. Well, the end may be nearer than that, as the director is mulling the idea that his ninth film, "Once Upon a Time in Hollywood," could be his last.

In a GQ Australia article about the upcoming movie, Tarantino said, "I think when it comes to theatrical movies, I’ve come to the end of the road."

He added, "I see myself writing film books and starting to write theatre, so I’ll still be creative. I just think I’ve given all I have to give to movies."

The article's writer, Jake Millar, then notes that this next film is "peak Tarantino, a movie about movies, set in the years that came to define Tarantino as a filmmaker." So why not make it his last, his masterpiece?

It's a question that set Tarantino thinking.

“If ["Once Upon a Time"] is really well received, maybe I won’t go to 10," the director mused. "Maybe I’ll stop right now! Maybe I’ll stop while I’m ahead. We’ll see.”

(Hmm, what does that mean for the "Star Trek" movie that Tarantino has been talking about making?)

Whether the director retires after this film or the next, he will definitely retire soon. As star Brad Pitt said, "No, I don’t think he’s bluffing at all. I think he’s dead serious. And I kind of openly lament that to him, but he understands the math of when he feels like directors start falling off their game. But he has other plans and we’re not going to have to say goodbye for a long time.”
