Continuity mistake: When Cho finds his mother dead she is sat on a wheeled platform of some kind. I'm not sure of its purpose and it wasn't present when she was killed. (00:43:35 - 00:45:06)
Visible crew/equipment: When Cho is fighting the thieves in the street one of them tries to smash a barrel over his head but Cho knocks him out and the man drops the barrel as he collapses. If you watch as the barrel drops you can see the shadow of the camera cast on it. It's too narrow to be anything else in the scene. (00:39:02)
Continuity mistake: When Braden gets out of his car in front of Caifano's building there is a close up shot of three doormen, the two on the left are stood very close together and one on the right is further away. Then cut to another angle and all three doormen are spaced differently. (00:19:47)
Continuity mistake: The blowdart pipe that Braden pulls out of his bag is totally different to the one he pokes through the slat of the curtain to kill his target. The one from the bag is bamboo and thick and the one he uses is black and much thinner. (00:26:26)
Revealing mistake: If you watch the scene when Caifano buys information off the homeless man, when his limousine pulls up on the pavement you can see people stood in the windows of the building behind watching the filming. (00:23:51)

(00:35:45)
Visible crew/equipment: After Cho jumps on top of the thug van and falls off the roof, hanging off the driver's side near the back of the van, the back corner of the film crew's truck bed is visible in the lower right corner of the screen for a moment. (00:39:10)
