Harrison Ford on his ‘Shrinking’ character’s Parkinson’s journey

He’s on the case. 

Harrison Ford said he’s not blasé about his “Shrinking” character, Dr. Paul Rhodes, having Parkinson’s.

When People asked how seriously he takes it, the “Indiana Jones” star replied, “Can I say deadly f – – king seriously?”

Ford, 82, co-stars in the AppleTV+ show, which is currently two seasons and has been renewed for a Season 3. 

Created by Bill Lawrence, star Jason Segel and “Ted Lasso” star Brett Goldstein, “Shrinking” follows Jimmy Laird (Segel), a therapist who, in the midst of grieving his wife’s death, crosses ethical boundaries to be overly honest with his patients. 

Ford’s character is one of his colleagues. His Parkinson’s diagnosis was revealed at the end of the first season. 

“There’s no intention to make it into a joke,” Ford told People.

“But there are people that absorb these kinds of experiences with grace and courage and a little bit of wisdom. And that is not to say that some people do not.” 

The “Star Wars” star added, “It’s just to say that this is a person particularly equipped to communicate what it is that it’s like, and that is something that I feel that is worth sharing with our audience.” 

Lawrence, 56, told The Post earlier this month: “The greatest gift of my professional career is getting to be involved in this stage of Harrison Ford’s career. It’s been really cool. He’s so conscientious. He’s so passionate.”

Lawrence said he thinks the role gets emotional for Ford, as the superstar is in his golden years.

“I think it gets emotional for him. I don’t think I’m talking out of school because we’re writing about a guy who loves his profession and is apprehensive about ever having to give it up,” Lawrence said.

“He’s brought an emotional level to it that I did not expect. And he’s kept it from feeling kind of disease of the week, trauma porn,” Lawrence shared of Ford’s portrayal of the psychologist.

“It’s really, really so respectful because Brett and I wrote about Parkinson’s because of my dad, Michael J. Fox, Phil Stutz and Brett’s father. Harrison’s given it such care. We were super, super grateful. Brett and me.”

Last month, Goldstein revealed on “Late Night With Seth Meyers” that the character is based on his father. 

“So my dad has Parkinson’s, and it wasn’t something we weren’t going to talk about publicly when we were talking about the show,” he explained. 

But, he said, Lawrence “let it slip” accidentally. 

After that, Goldstein shared, “I called my dad, and I was like, ‘Listen, Dad, Bill said about you having Parkinson’s. I hope that’s not a problem.’ And my dad said, ‘Are you telling everyone that I’m Harrison Ford?’ And I said, ‘Yeah,’ and he went, ‘F – – king cool. Go for it. Please, go for it.’”
