The Avengers' sixth season opened with an exciting harkback to the classic third-season episode "The Cybernauts." The plot is set in motion by the brother of the man whose earlier attempt to use robotic technology to take over the British economy was foiled by Steed and Emma. Thirsting for revenge, the villain conspires with a trio of shady scientists to transform the Avengers into "living puppets." Horror-film perennial Peter Cushing guest stars as the deceptively charming Paul Beresford. Written by Philip Levene, "Return of the Cybernauts" made its British TV debut on September 30, 1967; its first American telecast was delayed until an open timeslot was found on February 21, 1968. ~ Hal Erickson, Rovi
