Andrι the Giant: In the spring of 1986 (following his WrestleMania 2 battle royal victory), Andre requested time off to go on a tour of Japan, heal from legitimate injuries, and begin filming scenes from a movie he was hired to star in, The Princess Bride. At the time, he was engaged in a 3-year-old feud with Big John Studd over whom was the true giant of wrestling, and a storyline was contrived to have Andre "miss" several high-profile tag-team matches (with a partner of his choice) against Studd and King Kong Bundy. Eventually, at Bobby Heenan's behest, WWF president Jack Tunney "suspended" Andre. Later in the summer of 1986, a masked wrestler, identifying himself as the "Giant Machine" appeared, targeting along with other masked "Machine" wrestlers Studd and Bundy. The villains insisted that the Giant Machine was in fact Andre. They were right, except they were unable to mask Andre to prove his true identity (much to the delight of fans), and the WWF's lead announcers, usually Vince McMahon, Gorilla Monsoon, or Bruno Sammartino, speculated that the "Giant Machine" might be one of several famous Japanese wrestlers.
Indeed, Bundy and Studd never were able to prove their case to the fans, which had they succeeded Andre would have been "fired" (for circumventing Tunney's suspension). However, the storyline was always left open so that if Andre's health forced his retirement, the "Giant Machine" would have been unmasked. However, Andre's health held up enough and after finishing filming of The Princess Bride and concluding his Japanese tour he was "reinstated" ... and a heel turn later that led to his famous WrestleMania III match with Hulk Hogan etched his name in history.
At the height of the Bundy/Studd-Machines feud, Heenan introduced his own stable of "masked" wrestlers during a segment of "The Flower Shop." It was obviously Studd and Bundy wearing paper masks, and they quickly revealed themselves to scornfully mock Andre.
