Premise The series centered on a two-man troubleshooting team working for multi-national secret intelligence agency U.N.C.L.E. (United Network Command for Law and Enforcement): American Napoleon Solo (Robert Vaughn), and Russian Illya Kuryakin (David McCallum). Leo G. Carroll played Alexander Waverly, the British chief of the organization. Barbara Moore joined the cast as Lisa Rogers in the fourth season. The series, though fictional, achieved such cultural prominence that props, costumes and documents, and a video clip are in the Ronald Reagan Presidential Library and Museum's exhibit on spies and counterspies. Similar U.N.C.L.E. exhibits are in the museums of the Central Intelligence Agency and other US intelligence agencies. Thrush U.N.C.L.E.'s primary adversary was Thrush (WASP in the pilot movie). The original series never divulged who or what Thrush represented, nor was it ever used as an acronym. In the U.N.C.L.E. novels written by David McDaniel, it stands for the Technological Hierarchy for the Removal of Undesirables and the Subjugation of Humanity, described as having been founded by Colonel Sebastian Moran after the death of Professor Moriarty at the Reichenbach Falls in the Sherlock Holmes short story "The Final Problem". But in a second season episode, guest star Jessie Royce Landis plays a character who claims that she founded Thrush. Producer Felton always insisted that Thrush was not an acronym and stood for nothing. Thrush's aim was to conquer the world. Thrush was considered so dangerous an organization that even governments who were ideologically opposed to each other – such as the United States and the Soviet Union – had cooperated in forming and operating the U.N.C.L.E. organization. Similarly, when Solo and Kuryakin held opposing political views, the friction between them in the story was held to a minimum. Although executive producer Norman Felton and Ian Fleming conceived Napoleon Solo, it was the producer Sam Rolfe who created the global U.N.C.L.E. hierarchy, and he included the Soviet agent, Illya Kuryakin. Unlike the CIA or the British SIS (Secret Intelligence Service), U.N.C.L.E. was a global organization of agents from many countries and cultures. Innocent character The creators decided an innocent character would be featured in each episode, giving the audience someone with whom to identify. Despite many changes over four seasons, "innocents" remained a constant – from a suburban housewife in the pilot, "The Vulcan Affair" (film version: To Trap a Spy), to those kidnapped in the final episode, "The Seven Wonders of the
