In some parts of the world, the opening credits for the first color season begin with a brief sequence showing Steed preparing to open a bottle of champagne. Mrs. Peel shoots the cap off the bottle, and they pour a toast to each other. Only then do the opening credits actually begin.
American broadcasts of the 1965 season were preceded by an introduction showing Emma Peel and John Steed walking across a giant chessboard as a narrator says: "Extraordinary crimes against the people and the state have to be avenged by agents extraordinary. Two such people are John Steed -- top professional, and his partner, Emma Peel -- talented amateur. Together they are -- The Avengers!"
