Cast: Series 2 featured Patrick Macnee as John Steed in all 26 episodes. Either Jon Rollason (as Dr. Martin King, in 3 episodes) or Julie Stevens (as Venus Smith, in 6 episodes) accompanied him as noted in the table; with all of the other 17 episodes featuring Honor Blackman (as Mrs. Cathy Gale) accompanying Steed.

Series 4 (1965–1966)

Cast: Series 4 starred Patrick Macnee (as John Steed) and Diana Rigg (as Mrs. Emma Peel). It was the last series to be made in black-and-white, but also the first series to be shot entirely on film as opposed to mainly on videotape.

Episodes of this series were first broadcast in the UK on Tuesdays by Scottish Television, before ABC Weekend broadcast them four days later on Saturday.

A genie brings Steed and Emma to a fantasy world of cricket, harem dances, and creative assassination.

Starting with this series, the production budget was increased considerably, and 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 (airing in the US as Secret Agent) 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, and then later retracted this claim. Publicity photos of Elizabeth Shepherd as Mrs. Emma Peel survive.

For American broadcast, all episodes of the 1965–1966 series included a specially-shot prologue preceding the main credits, showing Steed and Mrs. Emma 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 closing credits of all episodes of the fourth series credit the production company as "Associated British Productions Limited", the name of ABC Weekend's parent company's film production wing in Elstree, but at the very end, the triangular logo of ABC Weekend TV appears with the caption "ABC production", as in previous series.

"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 (though the b/w sequence titled "Preamble for USA", written by Brian Clemens to introduce the item, which was to have featured Patrick Macnee and Diana Ring explaining/introducing this short colour test film, is either lost or was never filmed). 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 Macnee/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 (as John Steed) and Diana Rigg (as Emma Peel). From this series onwards, all episodes were filmed in colour, but as ITV did not begin colour transmissions until November 1969, all were originally broadcast in the UK in black and white.

Production of this series occurred in two batches. The first 16 episodes were broadcast in both the UK and the US from January to May 1967. The remaining 8 episodes were broadcast in the UK as a continuation of the fifth series from September to November 1967, but in the US they were delayed until January 1968 where they formed the first half of a new season.

Series 6 (1968–1969)

Cast: All episodes feature Patrick Macnee (as John Steed) and Linda Thorson (as Tara King). In episode 17, ("Killer") Tara makes a brief appearance before going on holiday. For the remainder of "Killer", Patrick Macnee as John Steed is paired with Jennifer Croxton as Lady Diana Forbes-Blakeney.

In episode 1 ("The Forget-Me-Knot"), Diana Rigg as Emma Peel makes her final appearance.

Patrick Newell (as "Mother") features in twenty of the episodes, with his mute sidekick "Rhonda" (Rhonda Parker) joining him for the latter eighteen.

The episode numbers in the table relate to the order in which they were first broadcast by Thames Television in the UK. Different ITV regions broadcast episodes on different dates and in different orders, so the Thames order does not match the order of first UK broadcast. Nearly all episodes in this series were shown, in a different order, in the US before they were shown in the UK.

John Bryce replaced Brian Clemens and Albert Fennell as producer for the start of series six. By the time Brian Clemens and Albert 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 (mostly without Patrick Newell as "Mother", and none with Rhonda Parker as "Rhonda") 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:

1. 20 March   The Forget-Me-Knot
2. 27 March   Invasion of the Earthmen
3. 3 April        The Curious Case of the Countless Clues
4. 10 April      Split!
5. 24 April      Get-A-Way
6. 1 May         Have Guns — will Haggle
7. 8 May         Look- (Stop Me If You've Heard This One) But There Were These Two Fellers..."

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 ones 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.

By the time the sixth series came to be broadcast in the UK, ABC Weekend TV had ceased to exist: it had merged with Rediffusion London to become Thames Television. However all episodes of this series were still credited to A.B.C. Television Films as had the previous series.

Notes:

• In the episode "Killer", Tara King is only seen departing for and returning from holiday. Steed's fellow agent for this episode is Lady Diana Forbes-Blakeney (played by Jennifer Croxton).
• In the US, the field/suits of armour opening title sequence was re-edited to 23 seconds (the UK sequence runs 49 seconds), to accommodate more commercials.
• The original 1968 German-dubbed episodes of this series had the field/suits of armour opening titles, but the 'Shooting Gallery' end titles.
• The original 1968 French-dubbed episodes of this series featured a variant in the opening title music: a gunshot sound is heard during the shot of Tara King running between two rows of suits of armour toward Steed, and the sound of the sword swipe at the beginning is missing.
• The original title music for the opening 'Shooting Gallery' sequence featured gunshots. The version of the episode "Split!"—the only episode featuring this title sequence—that is included in the current DVD release (and aired on TV channel True Entertainment in the UK) nevertheless retains the standard title music, with the opening sword swipe sound effect where the first gunshot should be.
