Chris Hemsworth is one of the main heroes of the Marvel Cinematic Universe, which helped him turn into a real star of action films and blockbusters. Hemsworth made his big-screen debut in 2009, playing a cameo role as James Kirk’s father, George Kirk, in the Star Trek reboot. But already in 2011, he got the role of Thor, which significantly increased the popularity of the actor. He is currently active with both Marvel and Netflix, and recently starred in the Disney+ documentary Limitless, directed by Darren Aronofsky.

In Limitless, Chris Hemsworth goes through various extreme tests designed to help the human body resist the aging process. It was in the fourth episode of the series that Hemsworth learned that he has a strong genetic predisposition to developing Alzheimer’s disease in old age. Both of his parents have the APOE4 gene, which researchers believe is an indicator of an increased risk of memory loss.

In light of the revelation, Hemsworth announced a brief hiatus from acting to spend time with his wife, Elsa Pataky, and their three children.

“It really triggered something in me to want to take some time off,” Hemsworth said in interview to Vanity Fair. “And since we finished the show, I’ve been completing the things I was already contracted to do. […] I’m going home and I’m going to have a good chunk of time off and just simplify. Be with the kids, be with my wife.”

After learning about his potential health-related future, the actor was surprisingly candid, and despite Disney’s offer to cut these scenes, decided to keep them in the film.

“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,” the actor said.

Even with this hiatus, Hemsworth has revealed that he is open to returning to the role of Thor in the future. “I’m open to it if there’s more,” the actor said, adding that he would be fine if this hypothetical Thor 5 was his last role as the God of Lightning.

“I feel like it’d probably be the finale, but that’s not based on anything anyone’s told me or any sort of plans. You have this birth of a hero, the journey of a hero, then the death of a hero, and I don’t know—am I at that stage? Who knows?” says Hemsworth.

One of the actor’s future big roles is in George Miller’s film Furiosa, a prequel to the famous film Mad Max: Fury Road.
