Chairman Peng
I love this movie, but there are some things about it that are downright silly. One scene that always bugs me is the exchange between the Chinese and Russian leaders and the new pope.
Chairman Peng insists that the pope take some sort of personal risk before he accepts his offer of help to feed the Chinese people. I can't imagine any sane world leader -- and say what you want about the Chinese Communists, but their leaders do tend to be smart and rational -- dictating such terms with his nation in the midst of a starvation crisis and on the brink of war.
Incidentally, Bert Kwouk (who played Chairman Peng as well as Kato in the Pink Panther movies and many other fine roles) is a largely underrated actor. He held his own in that scene very nicely next to the larger-than-life Olivier and Quinn.
