Michael J. Fox revealed that a frightening sequence from “Once Upon a Time in Hollywood” forced him to resign from acting.

Fox, 61, revealed more about his Parkinson’s disease journey in a recent interview with Empire Magazine, as reported by Variety. At the age of 29, Fox received a diagnosis in 1991, but he concealed it from his followers and the public for seven years.

Fox told the newspaper that during filming “The Good Fight” on CBS, he struggled to remember his lines. Fox’s problems reminded him of a moment from Quentin Tarantino’s 2019 film “Once Upon a Time in Hollywood,” in which Leonardo DiCaprio portrays an elderly Western star in 1969.

“I thought of ‘Once Upon a Time in Hollywood.'” There is a sequence in which Leonardo DiCaprio’s character loses his ability to recall lines. He returns to his dressing room and screams at himself in the mirror. “Just insane,” Fox told Empire Magazine. “I had this moment where I was looking in the mirror and thought, ‘I cannot remember it anymore.'”

Fox stated that the realization did not disturb him. Instead, he remained cool and told himself, “Well, let’s move on.” “It was peaceful.”

Fox’s comments come as his new film, “Still,” debuts on Apple TV+ on Friday. The documentary looks at Fox’s life with Parkinson’s disease, which the Parkinson’s Foundation defines as a neurological ailment that primarily affects dopamine-producing neurons in the brain.

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

“I simply wanted to keep my head underwater. I had to endure. “I needed to go as low as I could,” Fox explained.

In an April interview with “CBS Sunday Morning,” Fox stated that life with Parkinson’s disease is “getting tougher.”

“You don’t die of Parkinson’s,” Fox stated. “You die from Parkinson’s.” “So, I’ve been worried about its mortality. “I’m not going to be 80.”
