Inside the cave where Ting is fighting the thug who is armed with a large two-person saw, the thug is attempting to push the saw into Ting's throat and Ting is holding the saw at bay with his forearms. In another shot, Ting is using his right forearm and left palm to keep the saw at bay. In the very next shot, Ting is using both forearms again.
During the fight in the cave, just after Ting sees that George is being pulled up by a rope around his neck, two men attack Ting from the front and back. Ting kicks the man to his front in the head, jumping out of the way of the rear attack in the process; however, in the next shot the man behind him is down unconscious despite not having been hit.
During the tuk-tuk chase scene, Humlae's tuk-tuk reaches the end of the incomplete highway and the chasing vehicles fall over the edge. There are several shots as they fall and Humlae's tuk-tuk alternates between having one wheel off (low shot) and being fully on the highway (high shot). It is only after the initial chasing tuk-tuks have fallen off that his vehicle actually gets pushed halfway off.
At the end, in the cave, when Humlae is trapped, and Muay is attempting to free him, then shakes him, you can see his entire body is actually free and they could have pulled him out. The stuff on top of him is loose as well and shakes with him.
In the tracking shot of Ting being chased, just after he leaps over the children, the sound recordist can be seen holding his microphone and moving with the gang members on the right side of the frame.
There is one spot in the film where Ting, Humlae and Muay are eating on a street corner. Before this scene changes, it always freezes for a second, no matter what copy of the film you have or what DVD player you are watching it on.
During the cave fight with the thugs dressed in black, just after Ting hits the thug wearing the sleeveless shirt and head cap, during the slowdown scene to take out the thug you can see the thug's padding underneath his shirt.
Obvious stunt double when Humlae jumps through the wooden window to attack Don, and when Don throws him over the gas pump. Humlae's stunt double has a smaller head and more straight hair. Stunt double is used in both scenes.
