According to author William Goldman, when he was first trying to get the movie made in the 1970's, a then-unknown Arnold Schwarzenegger wanted to play Fezzik, and he was strongly being considered because Goldman could never get his first choice, Andre the Giant, to read for the role. By the time the movie was made about twelve years later, Arnold was such a big star they could not afford him, Andre was cast after all and the two big men had gone on to become friends.
