Other mistake: The old man executed in District 11 was shot in the head from behind. However, when Katniss looks out the window from above there are no blood stains on the floor, nor is there a gunshot wound to the head. (00:20:50 - 00:22:30)
Other mistake: While Katniss and Johanna are unreeling the wire on the way to the beach, it snags (or is deliberately pulled) behind a rock and Katniss tugs on it till it snaps. The wire was coming off a spool and becoming caught up would have no effect on how the wire unreeled, because the spool would keep on turning regardless. In fact, a taut wire behind her would be what she wanted. (02:05:35)
Continuity mistake: Prim's cat from the first movie is black and white. In this movie, it is orange. (00:04:30)
Continuity mistake: Just as Katniss is preparing to go on stage with Caesar, Joanne speaks to her backstage just as Katniss starts walking out. However from the view of the audience, Joanna is up on the platform with the other tributes. (01:10:30)
Audio problem: When the group is discussing why the Careers aren't on the beach, Beetee asks what happens at midnight and Katniss replies that the lightning strikes the tree. Beetee then says "Here's what I propose", but neither his mouth or jaw moves along with the line. (01:58:25)
Continuity mistake: In the training centre, after Brutus throws the spear and after Katniss has shot arrows at the enemies made of orange light (when the shot pans out) the weapons they used have disappeared and are not on the ground. (00:59:10)
Suggested correction: That's not a mistake but intentionally done to show the technology. It's not explained how it works, but the weapons disappear as it hits the targets.
Continuity mistake: When they bring the old man from District 11 to the front of the crowd to be shot down, after Katniss is dragged back inside the building, the old man turns his head to the right, to face the crowd. In the next shot, he's suddenly looking straight forward. (00:20:45)
Audio problem: When Plutarch tell Katniss she has 10 minutes to show her skills, the audio doesn't match his mouth. This is not due to him being behind a force field, as demonstrated earlier in the film. (01:04:50)
Continuity mistake: When Haymitch is talking to the head peacekeeper, the cut on the peacekeeper's forehead disappears in some shots and reappears in others. (00:36:10)
Continuity mistake: When Katniss starts to wrap the cable round the arrow she wraps it round the arrow head. Camera cuts and the wire around the arrow head has disappeared. (02:14:10)
Continuity mistake: When Peeta hands Katniss the pendant with the pictures open, the way the locket is positioned changes between the long shot and the close up of the pictures. (01:56:10)
Continuity mistake: When Cinna is attacked, he is hit against the glass, leaving blood on the tube. The blood is not present in any other shot. (01:19:00)
Continuity mistake: When Katniss has changed dress on the stage, she holds her arms out bent slightly at the elbow. Camera cuts and now her arms are completely outstretched. (01:12:25)
Continuity mistake: President Snow's backwash turns his champagne red. However in the long shot, it is still golden, with no hint of red. (00:30:00)
Continuity mistake: When the group is on the train and Effie is talking about getting each of them a gold token, Peeta's legs and arms keep moving between shots. (00:50:30)
Continuity mistake: When Katniss is assisting Ripper, she puts a cloth to her eye, holds it there with her right hand and looks back. When the angle changes, Katniss is looking back, but is no longer holding the cloth. (00:36:50)
Continuity mistake: When the spool of wire snags, the cable is running from the left hand (screen right) side of the spool. Camera changes and now the wire is running from the right hand (screen left) side of the spool. Despite the fact the wire is stuck and won't move. (02:00:35)
Continuity mistake: When Peeta hands Katniss the pearl, the amount of sand on his hand increases drastically instantly. (01:42:50)
Continuity mistake: When Katniss and co get attacked by the monkeys, she fires all her arrows or loses them in the water. We then see her run to the beach with the others. Still her quiver is empty. However, when Peeta gives her the pearl, she now has arrows. (01:42:00)
Suggested correction: When they're on the beach eating, almost an hour has elapsed. Plenty of time for her to get arrows, especially if they're by the cornucopia.
Continuity mistake: When the tributes are in the procession we see District 12's tributes still passing the drummers. Camera cuts and now they are a long way past the drummers. (00:56:25)
