One character gets an axe buried in their back and are killed.
Several prolonged fights scenes where characters viciously battle one another; though fast-paced and brutal, most of these fights are a bit comical and not too graphic.
Some people get set on fire. Jackie Chan burns his hands in one scene, and we see the burns. (This is what mainly gave the film its R-rating due to an unsimulated injury).
A man gets shot; some blood spurts.
A few bad guys get stabbed or slashed with a bamboo stick; blood is seen.
Jackie Chan vomits before the final fight.
