The 43-year-old actress has made a name for herself over the years in movies such as "Crash" and "Mission: Impossible II".
The actress, in a new interview with W magazine, recalled how the director asked her to do inappropriate things during an audition.
"I thought, 'OK, this is a little weird', but there was a female casting director in the room and I'd done weird stuff before so I did it."
"And he lurched away looking really shocked that he'd said that," she said.
When Newton's husband Ol Parker asked the man to explain what he meant, the producer said that "the director was showing that audition tape to his friends after poker games at his house."
The actress has decided to speak out about the incident in the hope of making other young actresses understand that sort of situation is unacceptable.
"One person will read this and it will stop them getting sexually abused by a director. That's the person I'm interested in.
