A friend of mine made a big Asian commercial with Oliver Stone a while back, and I recall him telling me that the CIA were still persecuting him over 20 years later for making JFK. I recommend this National Press Club presentation and Q&A because Oliver Stone has changed over the years but at this time he was really in the spotlight for shaking up the country and the context is brilliant.
Please note, we now know the Abraham Zapruder film was doctored, other than that most of the information is still on the money.
