Interesting Artifact circa 1973
This movie came out on the tenth anniversary year of JFK's murder. It did not pretend to be the 'answer' or solve who might have killed the president. What it did do was provide an alternative to the Warren Commission. Mark Lane was one of the major sources for Executive Action, and his extreme skepticism of the Warren Report was well known. What the movie does to an excellent degree is to provide a lot of exposition, explaining this and that via the discussions that the conspirators engage in.
Screen play was written by formerly blacklisted Dalton Trumbo and he does a fine job in getting the point across. The film's portrayal of the cold, cold heart of the Texas businessmen exposes the sentiment of this mega-rich big shots who thought and acted like they could do whatever they damn well pleased 'for the good of the country.'
A sentiment that exists today in many privileged and elitist circles. JFK's murder was so shocking and the FBI, which had unclean hands in their relationship with Oswald, rush to judgement (as Mark Lane would say), made a weak case for all that happened. Was there a conspiracy to kill JFK? Who knows? What is clear, is that after the murder, various agencies, particularly the FBI and the CIA, did everything possible to cover their askes.
J. Edgar Hoover's behavior was probably the worst of all, considering that Lee Harvey Oswald actually made a rucus at the Dallas FBI office around a week before the assassination, even leaving a note/letter filled with threats. The FBI had been shadowing Oswald and was aware that he was working in a building the Texas School Book Depository, overlooking JFK's motorcade route, yet did NOTHING. May not be a conspiracy, but it was total criminal and historical incompetence.
While we are at it, look at RFK, who outright lied to the Warren Commission, denying any knowledge of plots to kill foreign leaders, particularly Castro, which might have better informed the Commissions conclusions. RFK was not a conspirator, he just wanted to keep his and his brother's reputations clean. What we do know, is that RFK was a very polished bare faced liar.
Stephen King who wrote 11/22/63 a few years ago, says that he is 99 percent sure Oswald was the shooter ('follow the gun'). BTW people who are anti-conspiracy like to point to how long it has been since the murder, and if there were others than Oswald involved, they would have been outed by now. Maybe, but Jimmy Hoffa, Bugsy Segal, Tupac, Alan Dorfman, and Sam Giancana have all been murdered, and no one has been prosecuted in any of these cases. So, if important enough, Omerta rules.
Executive Action is not a flawless movie. But it is a compelling artifact of the time when it was written. All these years later it holds up as interesting entertainment. Compared to Oliver Stones JFK it is easier to sit through and enjoy.
