The Invisible Man is a Sci-Fi American television series starring Vincent Ventresca, Paul Ben-Victor, Eddie Jones, Shannon Kenny and Michael McCafferty. Somewhat more successful than previous television series involving invisible secret agents, it aired from June 9, 2000 to February 1, 2002, lasting two seasons. The plot revolves around Darien Fawkes, a thief facing life imprisonment who was recruited by a low-rent spy organization and given the power of invisibility via implantation of a special "Quicksilver gland" in his head. The gland allows Fawkes to secrete a light-bending substance called "Quicksilver" from his pores and follicles. The substance quickly coats his skin, hair, nails and clothes and renders him invisible. He can consciously release the Quicksilver, which then flakes off and disintegrates. However, the Quicksilver gland was sabotaged at its creation by scientist Arnaud DeFehrn to release a neurotoxin that accumulates in the bloodstream and causes intense pain, followed by antisocial behavior and psychosis. The host requires regular doses of "counteragent" to keep him sane and healthy, which is controlled by said government agency. This series lasted for two seasons, before being cancelled due to cost issues and internal bickering between the Sci Fi Channel and its then-parent company, USA Networks. The show's first season ran concurrently in first-run syndication as well as on Sci Fi.

Get Smart is an American comedy television series that satirizes the secret agent genre. Created by Mel Brooks with Buck Henry, the show stars Don Adams, Barbara Feldon, and Edward Platt. Henry said they created the show by request of Daniel Melnick, who was a partner, along with Leonard Stern and David Susskind, of the show's production company, Talent Associates, to capitalize on "the two biggest things in the entertainment world today"—James Bond and Inspector Clouseau. Brooks said: "It's an insane combination of James Bond and Mel Brooks comedy." This is the only Mel Brooks production to feature a laugh track. The success of the show eventually spawned the follow-up films The Nude Bomb and Get Smart, Again!, as well as a 1995 revival series and a 2008 film remake. In 2010, TV Guide ranked Get Smart's opening title sequence at No. 2 on its list of TV's Top 10 Credits Sequences, as selected by readers.

A Man Called Sloane is an American secret agent adventure television series that aired on NBC during the 1979-1980 television season. It was a Woodruff Production in association with QM Productions, and became the final series produced by Quinn Martin's company to debut. The series starred Robert Conrad as Thomas R. Sloane III, a freelance spy who takes on occasional assignments for UNIT, a secret American intelligence operation run by "The Director," played by Dan O'Herlihy. The secret entrance to UNIT headquarters was through a toy store. KARTEL was the evil secret organization that was UNIT's nemesis. Aiding Sloane's missions was Torque, his deadly right-hand man played by Ji-Tu Cumbuka. Torque had a mechanical hand with interchangeable parts that often helped during their assignments. The pair were also assisted by "Effie", a computer voiced by Michele Carey. A Man Called Sloane was an amalgam of elements from numerous spy series of the previous 15 years, including The Man from U.N.C.L.E., Mission: Impossible, and Conrad's own The Wild Wild West. One of the more expensive series produced during the season, it failed to gain an audience and was cancelled after 12 episodes were broadcast.
