I’ll be adding this site to my links section. What a treasure trove of information at this website!! This will help arm your debunking skills:

JFK, Oliver Stone’s controversial movie on the murder of President John F. Kennedy, championed the assassination probe of New Orleans District Attorney Jim Garrison, and accused elements of the federal government of conspiracy in JFK’s death.

But whether one believes that a conspiracy took the President’s life or not, how trustworthy and accurate is the information presented in Stone’s film?

The JFK 100 details one hundred of the most egregious errors in Stone’s film, presented roughly in order of appearance: 100 Errors of Fact and Judgment in Oliver Stone’s JFK.
