Although Hemsworth said “it’s not like I’ve been handed my resignation,” the actor is now 8 to 10 times more likely to develop the disease. Hemsworth’s grandfather is currently diagnosed with Alzheimer’s disease.

As for his own predisposition diagnosis, Hemsworth said, “It’s not a pre-deterministic gene, but it is a strong indication. Ten years ago, I think it was more thought of as determinant.”

Shooting “Limitless” not only made Hemsworth discover his genetic predisposition for Alzheimer’s, but it also led to the actor meeting with death doulas for the series final episode and confronting the end of his life. Hemsworth said all of these experiences inspired him to take time off from acting.

“It really triggered something in me to want to take some time off,” Hemsworth said. “And since we finished the show, I’ve been completing the things I was already contracted to do.”

“Now when I finish this tour this week, I’m going home and I’m going to have a good chunk of time off and just simplify,” he added. “Be with the kids, be with my wife.”

Hemsworth has already completed production on movies such as Netflix’s “Extraction 2” and George Miller’s “Mad Max: Fury Road” prequel Furiosa. The actor said that Disney offered him a version of “Limitless” that cut out the diagnosis, but he was adamant about leaving it in.

“If this is a motivator for people to take better care of themselves and also understand that there are steps you can take—then fantastic,” Hemsworth said. “My concern was I just didn’t want to manipulate it and overdramatize it, and make it into some sort of hokey grab at empathy or whatever for entertainment.”

Limitless is now streaming on Disney+.
