Lou was most familiar as the original Hulk, but before he made his way to the small screen, he worked as a professional bodybuilder who won IFBB titles for Mr. America and Mr. Universe. Thanks to a friendly rivalry with one of his colleagues Arnold Schwarzenegger he decided to appear on the acting map. Ferrigno and Arnold both starred in the 1975 docudrama Pumping Iron which showed the competitive world of bodybuilding. Thanks to the fact that Lou competed in the first-ever World’s Strongest Man competition (finished fourth by the way) he was cast as The Hulk in the CBS series The Incredible Hulk, and since then he mainly did guest appearances as himself and voiceover jobs.
