VIDEO- Dr. Perrodin explains why Historians feared radical change in what people thought about the assassination of President John F. Kennedy in 1963, due to Oliver Shone’s 1991 movie, JFK, which promoted a conspiracy that was already eroding the public’s “belief” in the reality of the Kennedy assassination. 

As Kenneth Boulding (1956) stated about the role of film and media on people’s memories…”These types of messages serve to confirm existing beliefs and add detail to images we already hold. A message can also have a profound impact, changing the image in a revolutionary way. We can discover new facts, encounter new theories about why an event happened, and have our convictions about a past “truth” weakened.”
