AAustralian actor Chris Hemsworth has been considered invincible as the god of thunder Thor in the comic book adaptation of the same name for more than ten years. Beyond the screen, the 39-year-old superhero actor was unexpectedly caught up in thoughts of his own impermanence. As Hemsworth said in a publicity appearance for the documentary series Limitless, doctors found an increased likelihood of Alzheimer’s disease during a blood test during filming.
“The thought of not remembering the life I had with my wife and children scares me the most,” the actor told ABC. “Limitless”, a production of the media company National Geographic, is the documentary continuation of Hemsworth’s screen myth. The series, designed by Darren Aronofsky, shows the Australian for six episodes in extreme conditions such as swimming in the ice-cold Arctic Ocean, climbing tours and hiking through the wilderness, of course without a map or mobile phone. For one episode, Aronofsky starved the actor for four days. “It was clear that this was going to be a particular challenge for Chris because he’s used to eating a lot of calories for ‘Thor,'” the filmmaker told Gizmodo blog.
