Dwayne Johnson 'not sure' if he'll do Fast and Furious 9 over Vin Diesel feud

Dwayne 'The Rock' Johnson is "not quite sure" if he'll star in Fast and Furious 9 due to a "fundamental difference" he has with co-star Vin Diesel.

The WWE legend has opened up about the high-profile quarrel in a new interview with Rolling Stone, although the article steered clear of his more vicious feud with Tyrese Gibson, another co-star.

Johnson's language is not as strong as in his infamous Instagram video labelling fellow Fast and Furious stars "unprofessional candy-asses", but the sentiment is similar.

"Vin and I had a few discussions, including an important face-to-face in my trailer," he told Rolling Stone.

"And what I came to realise is that we have a fundamental difference in philosophies on how we approach moviemaking and collaborating. It took me some time, but I'm grateful for that clarity, whether we work together again or not."

Although he adds he's not sure if he'll be in the next Fast and Furious movie, Johnson says his spin-off with Jason Statham is on track for release next year and he's concentrating on making it "as good as it can be".

As for his disagreement with Diesel, Johnson told Rolling Stone he harboured "no ill will" for him - then changed his mind and asked for that comment to be erased.
