Continuity mistake: At the reaping, As Effie says "our tributes from District 12" the camera pans from Peeta to Katniss. Katniss has her hair to the side of her left eye. Camera changes and now her hair is in front of her eye. (00:16:50)
Character mistake: In the first movie, Haymitch is their mentor. When they are eating dinner in the capital, Peeta says his mother said district 12 may finally have a winner, and she was talking about Katniss. What does he mean by "finally have a winner?" Haymitch had already won the games for district 12 in the past. So Katniss or Peeta winning wouldn't be the first for district 12.
Continuity mistake: When Katniss pulls back on her bow to take her first shot at the apples, she has a strand of hair hanging neatly by her eye. Camera cuts and this strand is now spread out and untidy. (01:32:30)
Continuity mistake: Just as Katniss is placed on her spot by Effie after walking up on stage, Effie grabs the microphone just as the camera changes. When the camera changes, she is no longer holding the microphone. (00:15:40)
Continuity mistake: As Katniss volunteers, the Peacekeeper on her right is stood next to her. We see Katniss from a raised angle and this Peacekeeper is now further away. (00:15:20)
Continuity mistake: When Katniss is looking at the forest on the TV screen her hair covers her one eye or it doesn't, depending on the camera angle. (00:35:20)
Other mistake: When we see the girl from 5 matching symbols, pay close attention when we see her hands. The squares selected are not pairs. But it accepted as a pair. (00:36:40)
Continuity mistake: When President Snow says Welcome for the first time he has both hands outstretched. Camera changes and one hand is now lowered. (00:32:40)
Continuity mistake: In the evaluation scene where Katniss shows off her bow and arrow skills, there are 4 arrows total. However, when she leaves, all 4 are gone, and she only shot 3.
Suggested correction: When she comes in, there are 5 arrows. She shoots 3 and when she walks away, you see 2 arrows left.
Factual error: At one point in the film, Katniss passes out after being stung by wasps numerous times. When she asks how long it had been upon awakening, Rue answers, "A couple of days." If she had been out that long, and as a result been unable to drink, she would be in very bad condition, not to mention the fact that she would immediately need to use the bathroom.
Suggested correction: You can help an unconscious person stay hydrated by gently pouring small amounts of water into their mouth. They'll swallow it by reflex.
Continuity mistake: As well as being an audio problem, the cannon sound representing the death of a tribute is not consistent. It goes off shortly after the bloodbath scene and the scene in which Peeta kills a girl. It doesn't go off for any other deaths though, such as when Rue dies.
Other mistake: When the children of District 12 are walking to the reaping, just after Prim receives the mockingjay pin, a boy can be seen wearing black and white converse shoes. (00:10:15)
Continuity mistake: You need to watch carefully for this mistake as it's over in the blink of eye. When in the training at the start we see the boy from District 8 fall off the monkey bars and hurt his leg. In the far shot that shows him falling we see him roll onto his back and grasp his shin just below the knee. Camera changes to him on his side and he rolls onto his back and grasps his leg again, but this time he grasps it a lot lower down the leg. (00:36:40)
