Clifford Marshall Thompson (October 18, 1904 - October 15, 1955) was one of the world's tallest men, and remains the tallest man to ever appear in a Hollywood film.
Although born in Rugby, North Dakota, as a child Thompson moved with his parents to Scandinavia, Wisconsin. He claimed to be 8 feet, 7 inches (2.62 m) and weigh 460 pounds (207 kg), but his actual height was about 7 feet, 5 inches (2.26 m). He was known as "The Scandinavian Giant," "The Wisconsin Paul Bunyan," and "Count Olaf". Thompson appeared in many Hollywood films, including A Day in the Life of a Giant and Seal Skins. Later he enrolled in Marquette University and earned a law degree.
A biography of Robert Pershing Wadlow recites that Thompson made a challenge to Wadlow to come to his hometown to prove that Robert was just 'another faker'. When both men walked on stage, Wadlow held out his arm and Thompson was easily under it. To which Wadlow replied "When you grow up you will be an awfully big boy."
