The accuracy of movies depend on the movies themselves and the filmmakers behind the project. Movies are often condensed adaptations of real life stories, events or people — so some details may be simplified or exaggerated for dramatic effect. Additionally, the artists’ interpretation of the facts can be different from other interpretations.
Some filmmakers strive for much more accuracy with their films, using techniques such as:
-Obtaining an in-depth understanding of the story they are adapting, researching all available related material
-Working closely with any living people relevant to the story
-Having experts advise on the accuracy of certain details such as costumes, artwork, or hairstyles
In most cases, viewers can use their knowledge of history or certain figures to identify any inaccuracies, giving them the chance to make their own judgement on whether a movie is accurate or not.
That said, the general consensus is that any movie can be classified along the following spectrum of accuracy:
-Highly Accurate: Includes films that are able to accurately depict every relevant fact or detail with practically no inaccuracies.
-Moderately Accurate: Includes films that may contain some factual inaccuracies, but generally does a good job in accurately portraying the general context of the story.
-Inaccurate: Includes films with significant factual inaccuracies and an overall disregard for the truth.
Ultimately, it's up to the viewer to decide how accurate a movie is based on their own knowledge of the facts and their level of interest in the story.
