Revealing mistake: Towards the end of the movie, when Steve Austin is on fire during the fight, you can see it is a stunt man wearing a burn suit for a split second.
Visible crew/equipment: When Jet Li and Sylvester Stallone are in the pick up truck just before the chase, the close up of them shows the reflection of the camera in the rear window. It is seen focusing and the lens rotating.
Continuity mistake: After the plane is docked Stallone and Statham enter the customs agency. Statham is wearing a Canon 5D MarkII camera on his neck with a small lens, he even shows it to the customs agent. After leaving the customs they walk across a square. The camera now has a big zoom lens attached to it. Statham is not wearing a lens bag. Where did he get that lense from? Also strange is that the lens is set in manual focus instead of automatic. Yet the picture stays focused even zooming in. This is not possible without looking at the screen. Plus the camera is turned off in the close up shot, with the image on the LCD composited in.
Continuity mistake: When the whole team flies to the island to rescue the girl, the plane body is black. However, when they fly back in the end of the movie, the plane has the "wildlife" inscriptions again.
Other mistake: When Statham has a 5d mark2 Canon camera there were a couple of mistakes in the close ups. At 29:58 the camera is actually off. At 29:55 it shows him twisting clockwise and you see the lens extend then it shows the lcd screen all zoomed in. But the lens he is using is a standard telephoto its only 24mm-70mm and he zoomed out to 24mm which is really wide. Plus that particular lens extends when it is at its widest unlike most other lenses.
Revealing mistake: When the guards enter the room where Sandra is tied to the chair, she kicks her leg out to fight them off but when the chair is tipped over, we see her feet securely tied together.
Continuity mistake: At the very end, after saying goodbye to the girl, when Stallone enters the cockpit he has a bulletproof vest on, when cameras change he doesn't have it and in the next angle he does have it on again.
Continuity mistake: In the scene where Lee pays a visit to Paul on the basketball court, he and Lacy are both wearing helmets. Lacy gets off the bike and after a little taunting, Lee drives forward. As he rides away from Lacy his helmet is on, there is a cut scene, and suddenly his helmet is off and Lacy is walking away with it.
