Did You Know?


The vast majority of the first series of The Avengers (1961) is sadly missing from TV archives and likely lost forever - only the first 15 minutes of this first episode and three complete later episodes, The Avengers: Girl on the Trapeze (1961) (which incidentally does not feature the character of Steed), The Avengers: The Frighteners (1961), and The Avengers: Tunnel of Fear (1961) (found in the hands of a private collector in 2016) have been recovered and preserved.

Third lost episode from season 1 turns up
28 April 2018 | by chongajulySee all my reviews

Episode 20, "Tunnel of Fear" now joins "Girl on the Trapeze" and "The Frighteners" as the only complete entries from season 1 to have survived, along with the opening reel of "Hot Snow," first discovered in 2016 and issued on DVD in April 2018. Happily, star Ian Hendry as Dr. David Keel is joined by Patrick Macnee's mysterious Steed on a case involving an injured prison escapee (Anthony Bate, later seen in "The Curious Case of the Countless Clues") seeking answers as to who framed him for the Southend funfair payroll some months back. Ingrid Hafner's Carol Wilson exits 10 minutes in, while it's the only time this season we get to see Douglas Muir's One-Ten, Steed's superior (the other four missing, five more next season), and the second and final appearance from Steed's puppy Juno, from "Ashes of Ashes" (first of three for Morris Perry). It's unfortunate that the villains are such a colorless and obvious lot, but there are two familiar faces among the onlookers in Steed's harem tent (disguised as the new barker), Nicky Henson and Julian Holloway. It's a fairly even split between Keel and Steed; the doctor spends most of his time with the escaped convict trying to reenact the crime when not evading the cops, while Steed's masquerade as harem barker is wholly successful, right down to getting knocked unconscious for his overly flirtatious nature. Here's hoping more hidden nuggets turn up again someday.
