Series 4 (1965-1966)
Two versions of The Town of No Return and The Murder Market were produced, one featuring Elizabeth Shepherd as Emma Peel and a remake after the role was recast with Diana Rigg. The Shepherd versions was never televised and is believed to be lost. Canal+ claimed they had the original versions, then later retracted this claim.

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.

The Strange Case of the Missing Corpse was filmed on the set of Honey for the Prince and was as Brian Clemens originally wrote it to be tagged on to the end of the final b/w episode transmitted in America advertising the upcoming colour episodes, it was also cut down into a trailer for the colour episodes coming soon to ABC Network in America. It was never meant to be screened in any other country. (just like the prologue to the b/w Rigg episodes.) There is a myth that it was to have originally been a twenty-minute mini-episode, the version presently available on video is three minutes long.

Series 5 (1967)
The Fear Merchants was the first episode of the Avengers to be produced in colour.
