John Steed and Cathy Gale

The Avengers

Originally, Steed (Patrick Macnee) was a recurring and somewhat minor character in the show. He assisted Doctor David Keel (Ian Hendry), the main star of the show. Hendry left the series. Steed was moved up in importance as Cathy Gale (Honor Blackman) joined the team.

Ms. Blackman, of course left the series to film ‘Goldfinger‘.
