I first watched this movie when I was 17 years old, when it debuted in 1970. Quite frankly, this movie, and many others, are so full of dialogue and information, that it was later when Cable TV was introduced, that I could watch several more times to
more fully understand what was going on.
The acting was outstanding, and specifically Richard Boone, who I only knew before from “Have Gun-Will Travel”, was the leading man, full of mystery, and he engages several operatives to help recover a letter that was sent to Peking China—by mistake.
Orson Welles & Max Von Sydow—and the man who plays a lover, Patrick O’Neil—-EXCELLENT!!
Watch a couple of snippets on YouTube, and then rent the movie!
