Michael J Fox has said that watching Leonardo DiCaprio in Quentin Tarantino’s Once Upon A Time In Hollywood inspired him to retire from acting for good.Fox was diagnosed with Parkinson’s disease in 1991 at the age of 29. He revealed the diagnosis in 1998 and in 2020, the Back To The Future actor said that he was beginning a “second retirement” after initially returning to work with the disease.In a new interview with Empire, Fox said his decision to step away was inspired by Tarantino’s 2019 film after once scene in the film reminded him of the issues he faced on a daily basis.Fox said when filming The Good Fight, a spin-off to The Good Wife, he struggled to remember his lines due to the disease.“I thought of Once Upon A Time in Hollywood,” Fox recalled in the interview. “There’s a scene where Leonardo DiCaprio’s character can’t remember his lines any more.“He goes back to his dressing room and he’s screaming at himself in the mirror.
