He was born, according to his official biographers, in a mountain cabin in North Korea in February 1942, an occasion marked by a double rainbow and a bright star.
But other records said he was actually born in Siberia in 1941, the BBC reported. His father had been exiled to Siberia.
He was believed to be a fan of Hollywood movies and reportedly had a library of 20,000 films, the BBC said.
Other official reports about Kim included claims that he had shot 11 holes-in-one the first time he picked up a golf club, that he could alter the weather just using his mind and that he had started walking at three-weeks-old and talking at eight weeks, London's Daily Telegraph reported.
Kim's official biography said that in elementary school he showed his revolutionary spirit by leading marches to battlefields where Korean rebels fought against Japanese occupiers of the peninsula.
By the time he was in middle school he had shown himself to be an exemplary factory worker who could repair trucks and electric motors, the biography claimed.
