The same actor who plays the President in Air Force One also plays Jack Ryan in some other movies. Jack Ryan later becomes President.
Remember that, before he became President, Jack Ryan was caught in a deadly trap in South America. Yes, Jack Ryan (the character, not the actor who plays him who, IIRC, is a member of the Hollywood left) would also have jumped into the fray.
By the way, according to the Telegraph, the Chileans were also involved in a shoving match with Chinese bodyguards accompanying their President Hu Jintao. The Chileans won that round: ,"Chilean guards were also involved in a shoving match with Chinese bodyguards accompanying President Hu Jintao at the Apec summit, successfully preventing the Chinese guards from following their head of state into a meeting with Mr Lagos."
Right you are about the China-Chile fracas. I read that one too.
I'm just giggling a little because I've never heard Harrison Ford referred to so anonymously! :-D "The actor who plays him." :-D
