Speaking to Australian GQ, he said: “I think when it comes to theatrical movies, I’ve come to the end of the road.

“I see myself writing 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.”

He added: “Maybe I won’t go to 10 [Once Upon A Time... will be hi ninth movie]. Maybe I’ll stop right now! Maybe I’ll stop while I’m ahead. We’ll see.”

In the same issue, the interviewer mentioned Tarantino's remark to Once Upon A Time... star Brad Pitt, who appeared to confirm it.

“I think he’s dead serious,” Pitt said.

“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.”
