Factual error: The film is set in Nairobi. It's all wrong, from the local language, not using Swahili, the car registration numbers are the wrong format, Kenya plates are like British, yellow at the back, not white. The skyline is wrong, and the drone view of the city map is wrong, the golf course is not the correct layout.
Continuity mistake: At the end, the blanket wrapped around the baby changes. In the wide shots, the red stripe is near the feet, but in the close up shots, the red stripe is around the body, next to Katniss' hand. And in the wide shot and first close up shot, the baby's right arm is lying on the blanket, but in following shots, the arm is under the blanket without Katniss doing anything.
Continuity mistake: Right at the beginning of the movie, the Sergeant pulls his jeep over and headbutts a prisoner who is carrying a Danish flag, seizing it. In the following shot he has his arms open and shoves away another prisoner, no flag in his hands. Next shot, he's standing by the bleeding prisoner, folded flag in hand. (00:02:25)
Revealing mistake: In one of the opening scenes the platoon of the captain is gunned down by a MG42. You can see the crimped fronts of the blanks in the belt.
