MinM's Journal - Thirteen Days (2000) is another good one...

Kevin Costner must have hit a little too close to home for the Pentagon's comfort with his Caesaresque portrayal of the relationship between JFK and his Joint Chiefs in Thirteen Days. BTW this excerpt from the Rolling Stone demonstrates Costner's level of interest in the JFK Case:

The Last Confessions of E. Howard Hunt

Around the time of st. john's Miami visit in 2003 to talk to his ailing father about JFK, certain other people were also trying to get things out of E. Howard, including the actor Kevin Costner, who had played a JFK-assassination-obsessed DA in the Oliver Stone film JFK and had become somewhat obsessed himself. Costner said that he could arrange for E. Howard to make $5 million for telling the truth about what happened in Dallas. Unbeknown to St. John, however, Costner had already met with E. Howard once. That meeting didn't go very well. When Costner arrived at the house, he didn't ease into the subject. "So who killed Kennedy?" he blurted out. "I mean, who did shoot JFK, Mr. Hunt?"...

The documentary Operation Hollywood laments the cozy relationship between Hollywood and the Pentagon. They note, at the 41:50-minute mark of Operation Hollywood, that Costner's Thirteen Days was one of the exceptions to that rule.

Another movie denied Pentagon cooperation, or as Amy Goodman puts it "The Access of Evil"

, was John Frankenheimer's Seven Days in May (1964). Which coincidentally enough also depicted JFK's rocky relationship with General Curtis LeMay, via Burt Lancaster's - Gen. James Mattoon Scott.
