Continuity mistake: Dre visits Han when he is smashing his car, and Han sits in the driver's seat; Dre sees the paper clip on the hood - the paper moves several times during the shots. From having a quite amount of glass on it, to no glass, to a little glass. And it switches positions three times.Stroemmen
Continuity mistake: In the scene where Master Li looks at his students bowing to Mr. Han, he is standing up in the crowd and a few moments later he is on the floor behind Mr. Han and Dre when they do their fist bump. In the alternate ending he was on the floor because he was beaten by Mr. Han in a battle, but in the original scene he just randomly appears on the ground. (02:01:20)
Continuity mistake: When Dre and Mei Ying are in the cafeteria for the first time, Dre puts his chopsticks in the small slot on the side of his tray. The angle changes to a front view of him setting his tray on the counter for lunch ladies and he puts his chopsticks on the tray a second time, now horizontally across the tray.
