Movies can affect how we remember history

Film has the power to misrepresent history in the collective memory of its audience, especially for younger generations who have not lived through any past events portrayed onscreen, according to Psychology Today. Indeed, studies show how believable misinformation can change memories, and in persuasion and social psychology, the “sleeper” effect is able to make people believe something they didn’t agree with or believe earlier. Doctor Alan D. Castel writes that in a perfect world, a recent example of alternate history like Quentin Tarantino’s Once Upon a Time in Hollywood (2019) would inspire viewers to research the facts behind the fiction.
