Continuity mistake: When Peeta asks what the plan is on the train, Haymitch is holding his glass by the top of the glass. Camera cuts and now he is holding it at the bottom of the glass. (00:22:55)
Continuity mistake: When Katniss and Rue are chewing on some bones just after the tracker jacker scene, Rue removes a bone from her mouth. Camera cuts and she removes the bone again. (01:27:40)
Continuity mistake: When Katniss dives into the water to escape the fire, a pocket of air forms in her coat and can be seen, as it should, on the surface of the water. Camera cuts and the air pocket has completely disappeared. There is no time for it disappear naturally and Katniss doesn't remove it. (01:16:20)
Continuity mistake: When Katniss gets a score of 11 Effie Trinket raises her hands. In the next shot she raises them again. (00:47:40)
Continuity mistake: When Katniss is volunteering to replace Prim, she struggles with 2 guards and starts to fall down. As such her head ends up lower than both guards' shoulders. Camera cuts and she is stood up again. This is an instant cut and a very bad edit. (00:15:35)
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)
Continuity mistake: When the announcer gives the second notice that there can only be one victor, Katniss is looking at Peeta. Camera cuts and she's looking the other way. (02:01:00)
Continuity mistake: At the end we see Cato with 2 hands Katniss' neck trying to choke her on the edge of the Cornucopia. Camera cuts and now he has one hand on the edge of the Cornucopia. (01:59:00)
Continuity mistake: When Katniss shoots the rock to draw the deer out of hiding her right hand is uncovered. Then as she fires at the deer a moment later a leather glove has appeared on her hand. (00:05:00)
Continuity mistake: Katniss puts her quiver on her shoulder for the very first time. Camera cuts and now it's across her back. (00:03:45)
Continuity mistake: In the first shot of the two girls at the very start, Katniss is stroking Prim's hair. She occasionally places her hand on Prim's head. However, when she does this, her hand is in a different spot in between camera cuts. (00:01:50)
Continuity mistake: When Katniss meets Cinna, he has 4 earrings in his left ear and 2 in his right, so the last shot (when he says that Katniss "shouldn't be dressed up in some stupid costume") is clearly inverted. (00:29:25)
Continuity mistake: Katniss pulls Peeta up onto the top of the cornucopia and you see him, albeit briefly, kneeling on the top. Camera cuts and he is now back to hanging from the cornucopia, being attacked by the dogs again. (01:58:40)
Audio problem: When Katniss offers to show off her flames, Caesar laughs and asks "what do you think folks?" however, his mouth, (which is facing away but his jaw is visible), doesn't move. (00:53:00)
Continuity mistake: When Haymitch is asking whats the hurry on the train, he has both hands up in the air (one with his glass in). Camera cuts to an angle behind Haymitch and his free hand, which should be visible in this shot, is not. (00:22:50)
