Battles B.C. also provides a good amount of history (some of which has been disparaged as inaccurate by various viewers) and information about ancient weaponry and strategy; for instance, in his campaign against the Gauls and their leader Vercingetorix, Julius Caesar pioneered a technique called “vallation,” erecting a wall around an entire Gallic town. Re-enactments combine real actors with computer-enhanced animation, but since the events in question took place thousands of years ago, the filmmakers largely eschew the use of flashy computer data screens and graphics seen in History Channel shows like Battle 360 and The Universe; the re-enactments are given a stylized, painterly treatment somewhat akin to that of the feature film 300, with on-camera experts weighing in frequently to set the scene. There are no bonus features. --Sam Graham
