The following works have links to the IMdB info., plus a McG scale of 1 - 5 with 5 being the films with the highest of quality and quantity of role for McGoohan. If you have a rating for a film I have not seen please send it to me - or if you disagree with my rating as it has been a while since I have seen some films. There are more clips on YouTube and interviews, I will try to list them also very soon.
