The most famous AVENGERS episode of them all
15 February 2011 | by See all my reviews

Look no further if you want to know which episode is the most famous, most acclaimed, and best remembered (to the tune of two sequels). Add the casting of venerable screen villain Michael Gough, whose sterling career paralleled that of Christopher Lee, except that Gough has had many more successes on stage, and even Broadway. Dr. Clement Armstrong may be confined to a wheelchair, but he's one of the greatest adversaries in the show's history, and Gough's assured confidence gives him a steely determination. "The Cybernauts" was the debut for Philip Levene, a prolific writer very much in tune with top writer/producer Brian Clemens, and the deft handling of horror, science fiction, and humor makes for an unbeatable combination (just don't mention it to a Cathy Gale purist). Although the third episode to be shown in Britain (October 14 1965), it was wisely chosen to introduce the series to American audiences (March 28 1966), and it was the US that determined the show's future. Gough would play a different role in "The Correct Way to Kill," while Frederick Jaeger, previously a villain in "Death of a Great Dane," would return as Benson in the sequel "Return of the Cybernauts," opposite the legendary Peter Cushing. Other veterans on hand include Burt Kwouk ("Kill the King" and "Lobster Quadrille"), Ronald Leigh Hunt ("Dragonsfield"), Gordon Whiting ("The Golden Eggs"), and John Hollis, previously seen in "Warlock," who went to do "The Superlative Seven" and "Legacy of Death." An actress who does NOT appear is Diane Clare, who actually appears only in the following episode, "Death at Bargain Prices," which also features a wheelchair-bound villain, Andre Morell (like Michael Gough, a renowned veteran of Hammer Films).
