JFK - The Movie
Interestingly enough, I've been watching the movie "JFK" on AMC tonight, which is the infamous rabble-rousing film directed by Oliver Stone that brought the assassination of JFK back into the spotlight over 15 years ago.
It's a great film, and if you've never seen it, you really should -- there are issues in the film that are based on fact (some are embellished a bit for dramatic license), some of which the public were never really clued into after the Warren Commission was concluded and published.
All in all, the assassination of John F. Kennedy began a new age in balancing the ultra-secret U.S. national security apparatus, the public interest, justice, and truth (although some are inclined to believe that we may never actually know what really occurred).
In any event, it's a very enjoyable film.
