I think this is a fascinating story. Doctor Zhivago is a hauntingly beautiful work --- one of my favorite books and films, certainly, and I am surprised by its importance as a political tool --- really, as a tool of propaganda! I found this story deeply interesting, and it notably answers questions and rumours that had been standing for fifty years. It's an important piece of journalism.
I now only wonder if the CIA had any similar involvement with the 1965 film...
