List of The Avengers (TV series) episodes


This is an episode list for the 1960s British television series The Avengers. The series was aired in Britain, on ITV, between 1961 and 1969.
The first four series were made in black-and-white; the first three were pre-recorded on videotape with occasional filmed inserts. Beginning with series 4 the series moved to all-film production, shot using the single-camera method. From series 5 onward, the episodes were filmed in colour.

Series overview

Series 1 (1961)

Note: The only episodes from the first series known to exist in complete form are "Girl on the Trapeze", "The Frighteners" and "Tunnel of Fear"; additionally, the first 20 minutes—the first reel—of the premiere episode, "Hot Snow", have been rediscovered and released on DVD. The most recent discovery was in 2016, when "Tunnel of Fear" was found intact in a private collection.

Note: Following series 1, a lengthy Equity actors' strike prevented development of the second series, and Ian Hendry decided to leave the show. When The Avengers eventually returned, its premise had been considerably retooled, with Macnee moved to the lead role, accompanied by an attractive and highly capable female sidekick, and a much more whimsical tone.

Series 2 (1962–1963)

Cast: Series 2 featured Patrick Macnee as John Steed in all 26 episodes. Either Jon Rollason or Julie Stevens accompanied him as noted in the table; with all of the other 17 episodes featuring Honor Blackman accompanying Steed.

Starting with this series, the production budget was increased considerably, location shooting was used extensively. With an eye toward getting the series shown on US television, the show was now shot using 35mm film instead of being videotaped, leading to an increase in picture quality. This brought The Avengers in line with other contemporary ITV series such as Danger Man and The Saint.
Actress Elizabeth Shepherd was originally cast as Emma Peel; one complete episode, "The Town of No Return", was filmed. Partway through filming of the second episode, "The Murder Market", the producers closed down production in order to recast the part. The Shepherd footage has never been televised and is believed to be lost. Canal+ once claimed it had the original footage, then later retracted this claim. Publicity photos of Shepherd as Mrs. Peel survive.
For American broadcast, all episodes of the 1965–1966 series included a specially-shot prologue preceding the main credits, showing Steed and Peel walking across a giant chessboard while a narrator introduces the characters and the concept of the series. This opening never aired in the UK and wasn't widely seen in the show's home country until the DVD release.
"The Strange Case of the Missing Corpse" was filmed in colour on the set of "Honey for the Prince" and was, as Brian Clemens originally wrote it, intended to be tagged on to the end of the final b/w episode transmitted in America to advertise the upcoming colour episodes. It was also cut down into a trailer for the colour episodes coming soon to ABC Network in America. Just like the prologue to the b/w Rigg episodes, it was never meant to be screened anywhere but the US. There is a myth that it was to have originally been a twenty-minute mini-episode, but the version presently available on video is three minutes long and doesn't appear to be missing any substantial narrative content.

Series 5 (1967)

Cast: This series featured Patrick Macnee and Diana Rigg. From this series onwards, all episodes are in colour, but as ITV did not begin colour transmissions until November 1969, all were originally broadcast in the UK in black and white.

John Bryce replaced Brian Clemens and Albert Fennell as producer for the start of series six. By the time Clemens and Fennell returned, three episodes had been filmed: two 90-minute episodes, named "Invitation To a Killing" and "The Great Great Britain Crime", as well as a standard-length episode, "Invasion of the Earthmen". These were considered to be extremely flawed episodes; they would likely have been scrapped, except that time did not exist in which to film new episodes and still meet the American contract. Hence, "Invitation To a Killing" was heavily edited and had several new shots filmed to become "Have Guns — Will Haggle", while "The Great Great Britain Crime" was heavily edited and had some old footage from previous episodes added, as well as some new footage, to become "Homicide and Old Lace". "Invasion of the Earthmen" was slightly edited as well. No known copies of the original versions of these episodes exist.
This series was produced in two batches: seven episodes were added to the last eight Diana Rigg episodes for broadcast in the US in the spring of 1968: this made up the third series on ABC in America. On the original American broadcasts, these episodes featured the original 'Shooting Gallery' opening/closing titles featuring Tara in a tight-fitting tan outfit with a short skirt, and gunshots as Steed and Tara are shot at by an unseen gunman, which was filmed by Harry Booth. The seven episodes that aired in the US in the spring of 1968 aired in the following order: "The Forget-Me-Knot" on 20 March, "Invasion of the Earthmen" on 27 March, "The Curious Case of the Countless Clues" on 3 April, "Split!" on 10 April, "Get-A-Way" on 24 April, "Have Guns — will Haggle" on 1 May, and "Look- But There Were These Two Fellers..." on 8 May.
These seven episodes were added sporadically into the 26 episodes produced in the next block, and the whole was transmitted in Britain as a single 33-episode run. The standard title sequences, the 'field/suits of armour' opening and 'playing card' ending, were filmed by Robert Fuest, originally for the first US transmission of the final 26 episodes, which made up the fourth series on the ABC network in America. These were tacked on to all 33 episodes when broadcast in the UK, apart from "The Forget-Me-Knot" which retained the amended Emma Peel opening credits and its original Tara King 'Shooting Gallery' end credit sequence.
