Best biography movie mistakes of 2016
Factual error: Throughout the first battle at "Hacksaw Ridge" some of the men are seen pulling the pins of grenades with their teeth. In actuality, the pins on the grenades (both modern and old ones) take at least 7 pounds of force to release the pin. If someone did that, they'd either cause severe damage to their teeth or maybe lose a couple.
Plot hole: When the group is walking through the jungle for the 2nd time, they have nothing more than their backpacks and a horse to accompany them. Suddenly we see them rowing down a river on a boat and raft. After making peace with the savages, when they have to let a group member go to get medical help, they have been washed ashore as they have been traveling on a single raft since the canoe was damaged by spear attack. How is it that they had a horse and an Indian guide to send away with their injured man?
Factual error: Women's stockings had seams in 1944. When people are dancing at the party in Bayfield's apartment, the backs of women's legs appear in enough shots to show that their stockings, anachronistically, are seamless.
Factual error: When Eakins returns to the house after he swears an oath to the union. You can see a thermostat on the wall behind him.
Continuity mistake: At the beginning, inside the hotel room in Hong Kong. Before Snowden puts the two cellphones belonging to his guests in the microwave, there are already two different cellphones lying in there. After the point of view switches to the microwave's turntable, the two original cellphones have magically disappeared.
