In the scene where we see an ancient battle taking place and see soldiers riding through the fighting on horseback, the extras and actors were prepped on the action, and kept a trail clear for the horses to pass through. Plastic horses were placed throughout the background to represent dead horses. The riders were stuntmen who were adept at rearing the horses. In the scene where we see a horse fall backwards, production used a fake horse for that scene.

Due to late notification and/or limited resources, American Humane Association did not monitor any of the dog action.
