Prisoner Who

It is rather odd how The Prisoner and the original series of Doctor Who have no writers or directors in common.

Lewis Greifer (who wrote the Prisoner episode "The General" under the name Joshua Adam) submitted the story that ultimately became the 1975 Who serial Pyramids of Mars, but the original version was deemed unusable and rewritten so completely by script editor Robert Holmes that what was ultimately broadcast was essentially a totally different story (and used the pseudonym "Stephen Harris"). So I don't think we can really count that. And Moris Farhi had scripts for both the very first season of Who and The Prisoner rejected... so it definitely could have happened, but it just didn't.

Anyway, there's a thought that was slightly too long to coherently express on Twitter. You're welcome to it.
