Pro Wrestling's Greatest Secrets are eight real-life professional wrestlers who wear masks and work under pseudonyms to conceal their true identities.

The reason given is that, by explaining wrestling's secrets (known as "breaking kayfabe" within the industry), their livelihood was at risk.

Pro Wrestling's Greatest Secrets was filmed mostly at an empty Grand Olympic Auditorium in Los Angeles, although an audience was present for some scenes.

[3] The World Wrestling Federation issued a statement about the special shortly before it aired, stating that "NBC has hired a bunch of bitter, masked wannabe 'pro wrestlers' that couldn't make the cut."

"[2] A review published by the Canadian Online Explorer was heavily critical of the special and wrote that it revealed nothing that fans didn't already know and that wrestling crowds willingly suspend disbelief.
