The Avengers is a spy-fi British television series created in the 1960s. The Avengers initially focused on Dr. David Keel (Ian Hendry) and his assistant John Steed (Patrick Macnee). Hendry left after the first series and Steed became the main character, partnered with a succession of assistants. Steed's most famous assistants were intelligent, stylish and assertive women:Cathy Gale (Honor Blackman), Emma Peel (Diana Rigg), and later Tara King (Linda Thorson). Later episodes increasingly incorporated elements of science fiction and fantasy, parody and British eccentricity. The Avengers ran from 1961 until 1969, screening as one hour episodes its entire run.
