Historical Accuracy Score
Extremely accurate overall
Minor dramatization prevents a perfect score
The film stays very close to the biography *American Prometheus* and historical records of the Manhattan Project.
Completely invented. No such private philosophical discussion occurred between Oppenheimer and Einstein.
Several real meetings with scientists, generals, and politicians were merged or moved in the timeline for dramatic pacing.
Many emotional conversations between Oppenheimer and his wife contain invented dialogue to heighten personal drama.
Dramatized for tension. The real countdown and atmosphere were less theatrical than portrayed.
Some of the political maneuvering and animosity was simplified and dramatized for clearer storytelling.
