Both Triple H and Chris Jericho have stated that they did not want their Undisputed WWE World Championship match to follow the match between Hulk Hogan and The Rock. Their feelings were that the Hogan/Rock match was the true main event and that no other match could top it. Triple H has claimed that WWE management insisted the WWE World Championship match be the last match of the evening, in order to preserve the title's prestige.
Bret Hart turned down an invitation from Vince McMahon to appear as a special guest referee at this event.
The 'fan' that Ric Flair attacked during the angle leading to his match with The Undertaker was actually Paul London.
Hulk Hogan competed in nine WrestleManias prior to this one, and this one occurred nine years after his last, which was WrestleMania IX (9).
This is the only WrestleMania where Hulk Hogan did not wrestle in red and yellow, wearing nWo colors instead.
