Louis Jude "Lou" Ferrigno (born November 9, 1951) is an American bodybuilder and actor. Ferrigno has appeared in such television series and movies as The Incredible Hulk (playing Bruce Banner's bulky alter ego, the Hulk), the bodybuilding documentary Pumping Iron, European-produced fantasy-adventures including Sinbad of the Seven Seas and Hercules, and most recently in the 2009 comedy I Love You, Man. He is best known for playing the Hulk, but more recently had a recurring role, as himself, in the sitcom The King of Queens.

Ferrigno was born in Brooklyn, New York to Matthew Ferrigno, an Italian American New York City Police Department Lieutenant, and his mother Victoria. As an infant, he suffered an ear infection and lost some of his hearing. Ferrigno started weight training at age 13, citing body builder and Hercules star Steve Reeves as one of his role models.

After graduating from Brooklyn Technical High School in 1969, Ferrigno won his first major titles, IFBB Mr. America and IFBB Mr. Universe, four years later. In 1974, he came in second on his first attempt at the Mr. Olympia competition. He then came third the following year, and his attempt to beat Arnold Schwarzenegger was the subject of the 1975 documentary Pumping Iron. Following this, Ferrigno left the competition circuit for many years, a period that included a stint as a defensive lineman for the Toronto Argonauts in the Canadian Football League.
