Continuity mistake: In the scene where Effie sings "Curtis, this time Effie's gonna win", Curtis turns his head a little to his left when Effie sings "win" at his face. But at the next shot, camera behind Curtis, Curtis' head is slightly turned to his right. (01:52:35)
Audio problem: When they are playing "Patience" for Curtis, he is holding a drink in his hand. After he shuts the music off, when he moves the hand holding the drink, you can hear ice clinking in the glass. However, you can plainly see that there is no ice in his drink. This happens a couple times in the scene.
