The Iceman is based on the true story of notorious contract killer Richard Kuklinski, nicknamed ‘The Iceman’. Michael Shannon stars as the real-life hitman who in 1986 was convicted of murdering 100 men for various crime organizations around the New York area. The twist to Kuklinski’s story was that he was also a devoted husband and father whose family was unaware of his real profession until his arrest, he was also a bona fide serial killer, having started killing people long before he took it up as a profession.
