In 1977, Ferrigno was cast as the Hulk in "The Incredible Hulk". Despite the fact that they were rarely on camera together, Ferrigno and Bill Bixby – who played the Hulk's "normal" alter ego – became friends; Ferrigno has described Bixby as a "mentor" and "father figure" who took him under his wing. Ferrigno also singles out the instances in which Bixby directed Ferrigno in some episodes as particularly memorable. Ferrigno continued playing the Hulk role until 1981—although the last two episodes were not broadcast until May 1982. Later, he and Bixby co-starred in three "The Incredible Hulk" TV movies.
