Michael J. Fox revealed that a frightening sequence from “Once Upon a Time in Hollywood” caused him to leave the industry.

Fox, 61, disclosed the information in a recent interview with Empire Magazine, according to Variety, in which he gave another glimpse into his life with Parkinson’s disease. Fox was diagnosed with cancer when he was 29 years old, but he didn’t notify his followers or the world for seven years.

Fox informed the magazine that he had trouble remembering his lines when filming “The Good Fight” on CBS. Fox’s difficulties reminded him of a scene from Quentin Tarantino’s 2019 film “Once Upon a Time in Hollywood,” in which Leonardo DiCaprio plays an elderly Western star in 1969.

“I remembered ‘Once Upon A Time in Hollywood.'” At one moment, Leonardo DiCaprio’s character is unable to recall his lines. He returns to his dressing room and screams at himself in the mirror. “It’s insane,” Fox told Empire Magazine. “I had this moment where I was looking in the mirror and thought, ‘I cannot remember it anymore.'”

Fox went on to say that the knowledge didn’t bother him. Instead, he remained composed and remarked to himself, “‘Well, let’s move on.'” It was tranquil.”

Fox’s remarks coincide with the release of his new film, “Still,” on Apple TV+ on Friday. The Parkinson’s Foundation describes Parkinson’s disease as a neurological condition that primarily affects dopamine-producing neurons in the brain, and the documentary examines Fox’s life with it.

Fox revealed in the video that he would spend hours in his bathtub with his head underwater because he believed he “needed to suffer” after his diagnosis.

“All I wanted was to keep my head above water.” I had to endure. “I needed to sink as low as I could,” Fox explained.

In an April interview with “CBS Sunday Morning,” Fox revealed that her Parkinson’s condition is “getting tougher.”

“You do not die from Parkinson’s disease.” “You die from Parkinson’s,” Fox explained. “So I’ve been thinking about its mortality.” I’m not going to live to be 80.”
