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.
Factual error: When Katniss approaches the gate to President Snow's mansion, just after the massacre of civilians in the large plaza, she sees her sister attending to wounded and runs toward her. There is a fiery explosion and Katniss is thrown onto her back and we see that radiant heat from the blast has caused the front of her coat to burst into flames. Flash burns are a common injury following an explosion, but Katniss has not a mark on her face, and not a trace of redness then, or shortly afterward when she is treated in a dispensary.
Suggested correction: As is made clear in the book, the fire never touches Katniss' face.
Factual error: The bunkers which are visible in the movie have not been prepped to look how they should in the years after the war. They would have been plastered and painted, not looking old and rusty as they appear in the movie.
