Paul W.S. Anderson’s Pompeii is not a film about the eruption of Vesuvius. It is a film about a slave-turned-gladiator and a merchant’s daughter whose love is thwarted by a corrupt Roman senator, and the eruption of Vesuvius happens to provide the third act. The volcano is plot device rather than subject. This is a reasonable choice for a commercial action film built on a historical catastrophe; it is not the choice that a serious engagement with Pompeii’s destruction would have made.
