The folks at the web site Flashbak alerted the world at large about the existence of this rare video with young Kurt Russell in the mid-1960s when he starred in TV ads for Mattel's line of generic spy toys under the banner Agent Zero-M. With the spy rage booming at the time, some companies decided to save the licensing fees they would have to spend to market official James Bond and Man from U.N.C.L.E. toys and simply made up similar items that they owned the copyright to. It should be noted that young Kurt also guest-starred in a first season episode of U.N.C.L.E.: "The Finny Foot Affair" broadcast in 1964 during the show's first season.
