I never said there was any actual connection, I just said with a little imagination you can see "Ice Station Zebra" fitting into the same universe because the movie version of "Ice Station Zebra" changes McGoohan's character from the book so that we never hear his real name. McGoohan is not a villain, he's a spy who ends up committing a screwup during the proceedigns because he gets led astray by Ernest Borgnine and ends up shooting dead an innocent man in Jim Brown because he trusted Borgnine when he shouldn't have. There is of course no actual connection in the writing/producing, but its a fascinating case how the viewer can easily *interpret* the three as running together.
I understand. I'll have to watch Ice Station Zebra again. I remembered McGoohan as being the villain in that film. As you describe him, then that was my interpretation from his not being the almost infallible hero he was in Danger Man... And yes, that kind of fatal screw-up could have lead him to try to resign the secret service fed up with it, not knowing that it was like trying to resign from the mafia... and end up as The Prisoner.
