Quentin Tarantino snapped at a female reporter at Cannes Film Festival Tuesday as he was questioned about his film “Once Upon a Time In Hollywood”.

The journalist, from The New York Times, asked the director why Margot Robbie didn’t have more to say or do as Sharon Tate in the flick.

However, Tarantino insisted after hearing the question: “I reject your hypothesis!”

As the reporter also addressed Robbie in the question, the actress said: “I think the moments I was on screen gave a moment to honour Sharon.”

“I think the tragedy was the loss of innocence. To show the wonderful sides of her could be done without speaking. I did feel like I got a lot of time to explore the character without dialogue, which is an interesting thing. Rarely do I get an opportunity to spend so much time on my own as a character.”

Tarantino then simply said “No” when asked by another reporter whether he had any doubts about depicting real-life figures such as Tate in the film.

The pair were also joined by Leonardo DiCaprio (who plays struggling actor Rick Dalton) and Brad Pitt (Dalton’s stunt double Cliff Booth) on the panel.

Pitt said of working with DiCaprio, “It was great ease, great fun. It’s that thing of knowing you got the best of the best on the opposite side of the table holding up the scene with you. We had similar experiences to laugh about. I hope we do it again.”

DiCaprio added of the film, “I think this movie is a love story to this industry. We studied people from Ralph Meeker to Eddie Byrne, all these actors whose work [Tarantino] really appreciates from an artistic perspective, who contributed in his mind to cinematic and television achievements.”

“That was most touching about the story. It’s a love letter to this industry we’re so fortunate to work in.”
