The blood on Kurt's stomach appears and disappears between the scenes during the final fight with Tong Po.
Towards the end of the second round, there is one sequence where Tong Po punches Kurt in the stomach 4 times, punches him in the face 3 times, punches him in the face 13 times rapidly, punches him in the stomach 9 times rapidly, and then does this double-fist type of move on his face. Tong Po's hands are covered in broken glass. In all probability, Kurt's face and stomach would resemble raw hamburger meat at this point, but he only has one major cut on his face and one on his stomach, both of which occurred earlier in the fight.
Before his fight with Tong Po, Eric has a hairy chest but in scenes during the fight it is clean shaven.
During the break in the opening fight, the corner man takes Eric's mouthpiece out of his mouth. When the round starts up again the corner man doesn't put Eric's mouth piece back in his mouth.

When Kurt is loading his brother into the van on the stretcher after the fight when he has just been paralyzed his feet are sticking out, but when the door is being shut he pulls them in.
During the final fight with Tong Po the tattoo on his left shoulder switches to his right shoulder signifying the shot had been flipped in post-production
When Kurt's brother is being rescued, his hands are tied behind his back and tries to fight off the attackers. Again, although being paralyzed, he manages to step with his left leg twice while sitting in the chair before the scene is over.
Taylor pumps the action of the M203 grenade launcher attached to his M16 prior to firing it, however, this would have ejected the grenade and rendered it useless.
When Tong Po delivers the devastating elbow to Eric, if you look carefully at the bottom of the
screen as Eric falls to the canvas, you can see The Director, David Worth's arm and the camera filming the previous action of Tong Po delivering the elbow from above Eric when he's on the floor.
The movie indicates at the end that everything is fine since Kurt won the fight. Sorry, but the bad guy fighter will have his people go hunt down and kill Kurt and his friends and family, just like he tried to do throughout the movie.
When Eric Sloane is captured and is being held, they hold him in a chair because he cannot walk. However, for a man with a spinal injury to sit straight up like that without slouching, the injury would have to be very low on the spinal column, much lower than where he was hit. People with lower spinal injuries still have a lot of problems with toileting and lower back support. Eric would be slouching and might fall out of the chair.
After Mylee cuts the ropes on Kurt's hands, Tong Po, a skilled, vicious and experienced fighter suddenly forgets how to block.
