"The Hitman" Bret Hart did not appear at this Wrestlemania, despite being one of the Hall of Fame inductees. He was uncomfortable being at this event. His name was mentioned a few times during the Pay Per View, and only footage from Survivor Series (1997) was used during the McMahon vs Michaels 'No Holds Barred' match up.
Mickie James' character at the time had changed from merely being a "fan" of Trish Stratus into a full-fledged "psycho" lesbian stalker, essentially the same role Tori (Terri Poch) had played in her storyline with Sable (Rena Mero) seven years earlier, but, Mickie found more success with it.
Kurt Angle's loss in the World Heavyweight Title match continued his 100% loss record in championship matches at WrestleMania, having also lost at Manias 16 (Intercontinental and European titles), 19 (WWE title) and 20 (WWE title). Angle however has a 100% win record in non title matches at WrestleMania, having won at Manias 17, 18 and 21.
Carlito, Finlay, Bobby Lashley, and Mickie James' first WrestleMania match. It was Finlay's WWE PPV debut and his first PPV appearance since "WCW Millennium Final" on November 16, 2000, and his first PPV on American soil since "WCW Uncensored 2000," since "WCW Millennium Final" was held in Germany.
