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.
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.
Continuity mistake: Johanna says to Katniss at the wedding, "don't you want Snow to see you dance?" When she does her facial expression is one with a smile, camera cuts and instantly her facial expressions are completely different from a smile, and he head is leaning the opposite way.
Continuity mistake: Katniss, Coin and Heavensbee are discussing Katniss staying in 13 and shooting some propo's to show she is still alive. Heavensbee has a pen in his hand that has the cap off. Camera cuts to Katniss and then back to Heavensbee and the pen lid is now replaced. In the shot of Katniss we see his arms and they do not make the motions of replacing the cap.
Continuity mistake: Pay close attention to the gun pointed at Katniss in the exchange on the railway tracks in district 2. There are 2 shots of the conversation, one facing Katniss and one from behind. In the shot from behind the gun barrel is not touching Katniss. However in the front shots it is. Also there are 2 strands of hair that keep moving between the two angles.
