Michael J Fox has revealed that he thought he might die whilst filming his new documentary.
The actor was in Bhutan in the Himalayas filming a documentary about optimism in the 'happiest place' earth and nearly fell down the mountain that he was climbing.
He told Wenn: "We hiked up to this place. I was feeling so good and so cocky about how great I felt and about how I could climb up there," he said. "I started to walk down the mountain, and five minutes down I started to wipe out. I just started running and I couldn't stop.
"I was going, 'I'm going to die. I'm not a yak. I can't stop'. I had to throw myself to the ground before I reached the cliff. I cut my arm up and cut my ring finger badly."
The actor, famous for his roles in Back to the Future and Casualties of War, suffers from Parkinson's Disease and is currently fighting the US Administration over Stem Cell Research.
The actor was diagnosed with the disease back in 1991 but only made public his battle with Parkinson's in 1998.
He had to semi-retire from acting in 2000 when his health worsened. But Fox found that being in Bhutan eased his symptoms.
He says, "They (people of Bhutan) really are (the happiest people). It's amazing. They're just beautiful people.
"I don't know whether it was the altitude or the thinning of the blood or whatever, but I had much less symptoms."
