We rate “based on a true story” movies for historical accuracy by comparing the film to real events, biographies, and trusted sources like History vs. Hollywood.
We evaluate each movie based on how accurately it portrays the core story and major real events. We do not penalize minor dialogue changes or small timeline adjustments made for cinematic pacing.
Accuracy Scale (out of 100)
A higher score means the movie stays closer to documented history. A lower score means it takes more creative liberties with major events or adds significant invented scenes.
