Audio problem: When Snakehead grabs the medallion from Jackie, Jackie screams in pain. However, any Jackie Chan fan can hear that it isn't actually Jackie screaming.

Revealing: When Watson is standing over Jackie's dead body and says "I'm sorry I wasn't there when you needed me most, my friend" you can see Jackie reflected in the TV standing ready for his queue before entering the picture.

Other: In the scene where Jackie meets the boss of the Interpol department in Ireland, he shows everyone some sketches, the child and then a man with a hat. If you watch the picture, it changes from a man with a hat to another man without a hat back to the man with the hat and once again back to the man without the hat.

Revealing: When the black guy is on the falling ladder, the ladder slows down as it nears the ground.

Revealing: When Jackie and Watson are discussing whether it's Jackie or not who's lying on the table, and Watson says "Well it's cold in here" it is obvious they are using a double for Jackie lying on the table. The double's nose is too pointy to be Jackie.

Continuity: At the hospital when Jackie and Watson are being shot at, Jackie pushes Watson through the door. We see Watson flying backwards out the door. When it cuts we see him come flying face first.

Visible crew/equipment: Eddie Yang chases a black man, who gets on a ladder. The ladder starts to tip over and a part of the set comes on screen at the base of the ladder.

Continuity: When Jackie and Watson are driving Watson's car right after they've been on a video conference with all the professors, they park the car. We see Jackie has his seatbelt on, but when it cuts to him breaking the door off the seatbelt is no longer on him. He could not have removed it that fast.

Continuity: On the "Sea Horizon" when Jackie says "I'll cover you" to his companion, you see his companion jumping over board while holding onto his machine gun. When it cuts to him just going over board his machine gun is hanging down.

Continuity: When Nicole realize that Jackie is dead she hugs Watson while grabbing him by his collar. When it cuts she is holding onto his towel instead.

Continuity: When Jackie and Nicole gets to Watson's house, Nicole hugs Charlotte and some of Charlotte's hair hangs over her left shoulder. When it cuts the hair is behind her shoulder.

Deliberate "mistake": When Jackie tries to avoid the Jamaican guy he jumps up to a higher deck. As we see him duck out of sight it takes him about 1 second to get to the other side and jump down there. However it's at least 40 feet to get to the other side. Jackie is usually fast but not that fast.

Continuity: In the beginning when Snakehead has received the book from the old man he says "The only pitiful is your life". He grabs a knife and we see him stretching his arm out against the old man. When it cuts Snakehead has his arm bent with the knife under the old mans chin. The way Snakehead stretched his arm he would have stabbed the old man right in the face, not placing the knife under his chin.

Continuity: When Watson is about to leave the office and says "It's your fault, that is" to Jackie, a man is standing behind Watson leaning against a board. When it cuts the man is gone.

Continuity: When Nicole is hugging Watson, Jai is nowhere in sight. But when Watson and Nicole stands up Jai is suddenly standing right behind them.

Continuity: When they open the container we see Watson run in first. When it cuts Nicole comes running first.

Continuity: When Jackie accidentally hits the door, making it fly through the air, the color of the door changes from light green to vanilla white.

Visible crew/equipment: When Jackie and Nicole gets to Watson's front door you can see a crew member reflected in the door.

Continuity: There is one point in the hospital scene where there's a close-up of the evil female nurse who shoots a quick glance behind her (towards us) and you can see that she looks nothing like she did moments earlier. In fact, she looks almost like a man.

Revealing: When the man who is eating hears Nicole knock on the door and he opens it, there is a shot from the top when she kicks him in the head. If you pause it when her foot has just hit the donut you can see that the person is a dummy.
