Fun Fact: A scene from "The Secret of Bigfoot" was recreated for the 2004 TV movie, Behind the Camera: The Unauthorized Story of 'Charlie's Angels' with Ben Browder playing Lee Majors (playing Austin) and John DeSantis as Bigfoot. DeSantis is only credited as "Bigfoot," not Andre the Giant nor Ted Cassidy. Like Cassidy before him, DeSantis is also best known for playing the character of Lurch, in The New Addams Family, a series produced in the late 1990s.
