At 1:56:56, following the initial battle, there is a low-angle shot of the generals seated on horseback that reveals the soles of their shoes; it is quite clear their footwear has trainer soles.
In one shot a sleeping baby is shown with blood flecking his face; in the very next shot his face is entirely clean.
Whilst Zhou Yu is receiving treatment for an arrow wound, his chest is drenched in blood. In the next shot the blood has vanished, although no one is shown wiping it away.
(Approx. 45 mins (American version)) During the tortoise battle, one of the generals pulls his spear out of an enemy's chest. Unsurprisingly the shaft is smeared with blood when he first seizes it, yet in the following shot it appears entirely clean.
The closing shot presents a double rainbow positioned beside the sun. However, a rainbow can only be visible when the sun is behind the observer.
