Revealing mistake: When Jack says "Screw you" to Sergeant Sykes, Sykes pulls his pistol and shoots Jack. You see the gun flash, and you see an impact on Jack. But if you watch closely, they do not line up. The special effects charge goes off indicating the hit on Jack's right breast. But when the gun goes off, while still moving, at that moment it was pointing at Jack's lower left abdominal region.
