Shawn Michaels wrestled the main event with a serious back injury. This was his last wrestling match for over four years.
WrestleMania XIV was the first WWF show where The Rock said his now famous catchphrase "Smell what the Rock is cooking'?" during an interview with Gennifer Flowers. He looked at Gennifer and said "If you smell what I'm cooking" It would morph into his famous catch phrase from there.
This event marks the final appearance of the "winged eagle" WWF championship belt. This particular design had been in use since WrestleMania IV (1988).
The referees that Ken Shamrock took out after his match were not real referees, but rather, local independent wrestlers in referee outfits. After SummerSlam 1997 (in which Shamrock did the same thing), it was decided not to put the real referees in danger like that again.
Luna Vachon reportedly had a hard time when she trained with Rena Mero (Sable) for their match; Mero refused to learn how to take bumps and Vachon was told by WWF management that hurting Mero in the ring would put her job in jeopardy.
