The 79-year-old movie star cemented his status as a sex symbol after playing hunky leads in action movies like White Lightning and Smokey and the Bandit, but in real life he has struggled sexually, due to the stress his body endured on set.
"I did all my own stunts, which is why I can't walk very well now," he revealed on U.K. talk programme The Jonathan Ross Show. "At certain times in the morning I regret it, trying to get out of bed. I can point to certain places and know it’s from certain pictures (I've made).
"It’s very embarrassing if you’re with a woman and you go to throw her over the other side of the bed and your knee goes out."
As Burt approaches his 80s in February (16), he finds himself contemplating the events of his life with intensity.
The actor started crying while talking to Ross as he detailed the conflicted relationship he had with his father, a police chief, named Burton, who passed away in 2002.
"He would never say I love you," Burt recalled through tears. "He was from a generation that didn't hug, kiss and say I love you. But he did finally say, 'I'm proud of you', and that was enough for me. It makes me cloud up when I think of when he said that to me. He was my hero."
Burt picked up a reputation as a womaniser during his heyday in Hollywood and in the 1980s he was at the centre of speculation suggesting he had contracted the HIV virus after losing a significant amount of weight, but the actor insists his gaunt look was the result of a broken jaw, which left him unable to eat solids.
However, the HIV health rumours stuck, and cost him many close friends: "It was an interesting time and that’s when you find out who your friends are."
