He is the only man to have been inducted into the WWE Hall of Fame, the WCW Hall of Fame, the Professional Wrestling Hall of Fame, the NWA Hall of Fame, the Hardcore Hall of Fame, and the Wrestling Observer Newsletter Hall of Fame. Funk was a primary subject of the documentary film Beyond the Mat. Funk is often noted for the longevity of his career, which has included multiple "retirement" matches.
