The Prisoner

McGoohan stated in a 1977 interview that, during the filming of the third series of Danger Man, he told ITC Entertainment managing director Lew Grade that he wanted to quit working on Danger Man after the filming of the proposed fourth series.

In a 1988 article in British telefantasy magazine Time Screen, though, McGoohan indicated that he had planned to pitch The Prisoner before speaking with Grade.

In the 1977 account, McGoohan said that Grade approved of the show despite not understanding it, whereas, in the 1988 account, Grade expressed clear support for the concept.

For example, Dave Rogers, in the book The Prisoner and Danger Man, said that Markstein claimed to have created the concept first and McGoohan later attempted to take credit for it, although Rogers himself doubted that McGoohan would have wanted or needed to do that.

Majority opinion credits McGoohan as the sole creator of the series, but a disputed co-creator status was later ascribed to Markstein after a series of fan interviews were published in the 1980s.

Some sources indicate that McGoohan was the sole or primary creator of the show.
