McMahon's vision for his promotion was starting to become possible when he signed AWA talent Hulk Hogan, who had achieved popularity outside of wrestling – notably for his appearance in "Rocky III" as Thunderlips. McMahon signed Rowdy Roddy Piper as Hogan's rival, and shortly afterward signed Jesse "The Body" Ventura. Other significant wrestlers who were part of the roster included: Big John Studd, André the Giant, Jimmy "Superfly" Snuka, "The Magnificent" Don Muraco, Junkyard Dog, "Mr. Wonderful" Paul Orndorff, Greg "The Hammer" Valentine, Ricky "The Dragon" Steamboat, and Nikolai Volkoff. In 1984, Hogan was pushed to main event status. He defeated WWF World Heavyweight Champion The Iron Sheik at Madison Square Garden on January 23, 1984 and thus evolved into one of the most recognizable and popular faces in professional wrestling.
