Daniel Day-Lewis is the only man to win three Academy Awards for Best Actor, a feat largely attributed to his extreme dedication to 'Method Acting.' For his role as Christy Brown in 'My Left Foot' (1989), he refused to leave his wheelchair for weeks, forcing crew members to spoon-feed him and carry him across the set. While filming 'The Last of the Mohicans,' he lived in the wild, hunted his own food, and learned to skin animals. For 'Lincoln' (2012), he insisted everyone on set address him as 'Mr. President' and spent a year researching the 16th President's specific high-pitched voice. His commitment was so intense that he often suffered physical health issues during production. After finishing 'Phantom Thread' in 2017, he famously retired from acting, stating that the psychological toll of inhabitating other people's lives had finally reached its limit.
