Parkinson's condition has affected Michael J. Fox's acting choices.
The actor and research advocate said memorising lines has been harder in the decades after he was afflicted.
"When I performed 'The Good Fight,' I couldn't recall the lines. I had a blank, I couldn't recall the lines, comparing it with early in his career when he got a screenplay for films like Family Ties.
"I had 70 pages of dialogue on a [Brian] De Palma movie, and knowing that an expensive Steadicam shot hinges on my memorising the lines — no sweat."
Fox had learnt to adapt and remembers a difficult scenario from "Designated Survivor"
Fox: "I couldn't understand the legalese." "I didn't panic, which was wonderful." No panic. I said, "Oh well." "Moving on"
Fox no longer takes line-heavy projects.
