Hulk Hogan, due to his appearance in Rocky III had a national recognition that few other wrestlers could offer, which is what led McMahon to sign him. Roddy Piper was brought in, as well as Jesse Ventura (although Ventura rarely wrestled in the WWF at that point due to the lung disorder that caused his retirement, moving to the commentator booth alongside Gorilla Monsoon). André the Giant, Jimmy Snuka, Don Muraco, Paul Orndorff, Greg Valentine, Ricky Steamboat and the Iron Sheik rounded out the roster. Hogan was clearly McMahon's biggest star, but there was debate as to whether the WWF could have achieved national success without him.

According to several reports, the elder McMahon warned his son: "Vinny, what are you doing? You'll wind up at the bottom of a river." In spite of such warnings, the younger McMahon had an even bolder ambition: the WWF would tour nationally. Such a venture, however, required huge capital investment; one that placed the WWF on the verge of financial collapse. The future of not just McMahon's experiment, but also the WWF, the NWA, and the whole industry came down to the success or failure of McMahon's groundbreaking concept, WrestleMania. WrestleMania was a pay-per-view extravaganza (in some areas; most areas of the country saw WrestleMania available on closed-circuit television) that McMahon marketed as being the Super Bowl of professional wrestling. The concept of a wrestling supercard was nothing new in North America; the NWA had been running Starrcade a few years prior to WrestleMania, and even the elder McMahon had marketed large Shea Stadium cards viewable in closed-circuit locations. However, McMahon wanted to take the WWF to the mainstream, targeting the public who were not regular wrestling fans. He drew the interest of the mainstream media by inviting celebrities such as Mr. T and Cyndi Lauper to participate in the event. MTV, in particular, featured a great deal of WWF coverage and programming at this time, in what was termed the Rock 'n' Wrestling Connection.
