Classic British 60s tongue-in-cheek spy TV show featuring Patrick McNee as Steed with a variety of sexy, sophisticated and intelligent sidekicks.
The most famous of these was Diana Rigg as Emma Peel. But other actresses included Honor Blackman and Linda Thorson.
Updated in the 70s as The New Avengers with Steed, Joanna Lumley as Purdey and Gareth Hunt as Gambit and also as a disastrous 90s Hollywood film with Ralph Fiennes and Uma Thurman.

In France it is called a completely different name: Chapeau Melon et Bottes de Cuir or Bowler Hat and Leather Boots.
