I’ve run into a couple of people who have never actually seen The Prisoner, so click the link to get started with getting acquainted with the show. See also here (via Hit & Run, which also has the intro to the show) for more details.
It is interesting to note that, in an era and culture where divorce is exceptionally easy and accepted, both Patrick McGoohan and Ricardo Montalban married once, and for life (over 50 and 60 years, respectively). Nice to see that this still happens, even in Hollywood.
