The vast majority of the first series of The Avengers
(1961) is sadly missing from TV archives and believed probably lost forever - only the first 22 minutes of this very first episode and two complete later episodes, The Avengers: Girl on the Trapeze
(1961) (which incidentally does not feature the character of Steed) and The Avengers: The Frighteners
(1961) have been recovered and preserved. See more
