Factual error: At the beginning of the scene where Katniss fights Clove after getting the backpack with Peeta's medicine, Clove throws a knife at her, and it cuts her forehead. If someone gets even a tiny scratch on his/her forehead it bleeds a lot, so a cut this big should at least blind Katniss with all the blood pouring from it (as the book says). But after struggling and running for her life, there's not a single drop of blood on her, and when Peeta rubs the medicine on her forehead, it is as if the wound was days old.
Continuity: When Katniss, Peeta and Cato are on top of the Cornucopia, the blood stains on Cato's hand keep disappearing and reappearing when the camera switches between Cato and Katniss.
Other: When Katniss, Peeta, and Cato are on top of the Cornucopia (after being chased by the mutations), near the end of the film, Katniss aims an arrow at Cato while having Peeta in a headlock. Katniss has her arrow fletchings on backwards. This would prevent her from shooting straight.
Continuity: Before Peeta throws the big metal ball in the training room, Marvel, Clove, and Cato are watching him. But after Peeta throws the ball, the camera shows Marvel, Glimmer, and Cato. Clove and Glimmer have switched places.
Continuity: During the scene when Katniss is looking for Peeta, Katniss wades across the river. When she steps out she is wet up to her thighs. When the camera changes directions, and she sees the blood, her bottom half is dry, even though she was just in water.
Continuity: As the tributes' chariots roll into the stadium, the Capitol citizens are throwing flowers to the tributes as they pass. When all the tributes are gathered at the end of the roadway, an overhead shot is shown and the runway is clean and flower-free.
Continuity: When Katniss and Peeta are told there can only be one winner, not two, Katniss drops her bow and arrows by her side and they do the bit with the berries. It is announced that both Katniss and Peeta are both winners, the ship flies overhead, and the camera looks down on the two of them. Katniss's bow and arrows are nowhere to be seen on the ground, even though it's a wide shot and they haven't moved.
Continuity: In the scene where Katniss uses the remote to change the scene in her bedroom window in the Capitol, her hair starts out stringy (having just been taken out of the braids she wore in the opening ceremony) and changes to full and beautiful and switches positions around her face and shoulders as the scene progresses.
Continuity: When Katniss is looking at the scenery in her room, she has some hair blocking her left eye. When the camera goes back to her, it is not blocking her eye anymore.
Continuity: When Katniss is sleeping up in the tree before the wall of fire starts, her sleeping bag has vanished - in the shot just before that she had it on.
Continuity: In the scene where Katniss is in her suite and has the remote in her hand, she gets up and moves to the wall. The shot is of her back and her hands have no remote in them. Yet in the next shot, she has turned off the scenery with the remote.
Continuity: When Katniss is saying goodbye to Gale in her cabin (just before leaving for the games) there is a small curl of hair hanging down the left side of her neck that can be seen in all the shots when the camera is behind her. Whenever the camera angle changes to a face shot the curl of hair disappears.
Continuity: When Rue dies, her mouth is open. When it cuts to the next shot of Katniss singing to her, her mouth is closed.
