Be warned - some versions are still available in the West which include a slow motion shot of a horse being deliberately tripped and rolling forward on its neck. As it's shown in slo-mo, it is particularly harrowing. Sadly, much of the horse action is difficult to stomach.
Some heavy battle violence, with spraying blood and falling horses. Characters are stabbed with lances, and a character loses a hand. The villain sends several rafts piled with typhoid-infected corpses, inflicting the heroic soldiers who try to bury the bodies. There's also plenty of martial arts-related violence, and a scene in which a tremendous fire spreads across a fleet of ships, causing untold damage and death.
