Overview
Danger Man (retitled Secret Agent in the United States for the revived series, and Destination Danger and John Drake in other overseas markets) is a British television series that was broadcast between 1960 and 1962, and again between 1964 and 1968. The series featured Patrick McGoohan as secret agent John Drake. Ralph Smart created the programme and wrote many of the scripts. Danger Man was financed by Lew Grade's ITC Entertainment.
Series development
The idea for Danger Man originated with Ralph Smart, an associate of Lew Grade, head of ITC Entertainment. Grade was looking for formats that could be exported.
Ian Fleming was brought in to collaborate on series development, but left before development was complete. Like James Bond, the main character is a globetrotting British spy (although one who works for NATO rather than MI6), who cleverly extricates himself from life-threatening situations and introduces himself as "Drake...John Drake."
Fleming was replaced by Ian Stuart Black, and a new format/character initially called "Lone Wolf" was developed. This evolved into Danger Man.
