Revealing mistake: When Jin is walking through the train station with his granddaughter, right before Ling is shown standing at the ticket booth, a few of the extras that Jin walks past can be seen looking at the camera. (03:36:45)
Revealing mistake: When Ling takes out her phone in the hotel bedroom, the time on the phone is 11:03. Given that daylight can be seen, the time must be 11:03am, but by this point in the story, it should be afternoon at the very least. Clearly, the scene must have been filmed in the morning. (02:15:40)
Revealing mistake: After Jin beats up the two thugs with the pool cue, it cuts to Cheng walking down the street and on the phone. After getting off the phone, he continues walking, and some of the background extras can be seen looking at the camera as they walk past. (01:49:10)
Revealing mistake: When Jin and Bu are confronted by the dog owner, Bu is standing on the right side of the frame. Then suddenly, Bu ducks down in front of the camera and repositions himself on the left side of the frame. Presumably, the actor was standing on the wrong side of the frame and had to reposition himself and ducked down because he didn't want to get in the way of the camera but unintentionally got caught doing so. (01:26:20)
Revealing mistake: When Bu is packing up his things in his bedroom, the camera appears to sway abruptly from side to side two or three times during the scene, almost as if the cameraman couldn't keep the camera steady. (00:57:25 - 00:57:50)
