science fiction elements, such as the artificially-intelligent super-computer of "Complex", the Russian soldiers revived from suspended animation in "K is for Kill", the submersible Russian community in "Forward Base" and the superhumans of "The Gladiators". Other episodes of that season dealt with more realistic plots. The Avengers and The New Avengers scriptwriter Dennis Spooner said that at the end of its run The Avengers had gone as far as it could in terms of parody. For this reason, producer Brian Clemens intentionally aimed for real stories and straight, Len Deighton-type spy stories in The New Avengers. Spooner explained that "it's no good saying 'I don't like The New Avengers so much, because it wasn't like the old show'-because it never could have been. We did everything – we did the kitchen sink! – and there was no way of going back on it". When reminded of his The New Avengers script "Gnaws", Spooner admitted that "well, yes, towards the end we relaxed a bit!" Some of the storylines used in the series were recycled from earlier scripts penned by Clemens or Spooner from other series. "Medium Rare" was based on the episode "Murder in Mind" of the British series Thriller, and "Gnaws" was based on the Thunderbirds story "Attack of the Alligators!"

Ian Hendry, who in the early 1960s had played Steed's original partner, David Keel, also guest-starred in one episode, "To Catch A Rat", playing a different role. "Obsession" features two of the stars of the Brian Clemens/Albert Fennell British crime-fighting action series The Professionals: Martin Shaw and Lewis Collins. Two series totalling 26 episodes were produced, which were aired on CBS in the United States, CTV in Canada, ITV in Britain, RTÉ in Ireland, ABC in Australia, TF1 in France, TVE1 in Spain and in syndication elsewhere. Laurie Johnson, who had composed the theme used from 1965 onward for the original Avengers series, returned to compose a new, updated theme for the revival, although it
