These are examples of the depiction of Celts, Gauls, Picts, Huns, Vandals, Goths, and other iron-age barbarbarians: the enemies, or allies, of Rome on its North-West frontiers, and their immediate post-Roman successors. So very crudely European barbarians from the first century BCE through to the fifth century CE.
Amazons and Gladiators: Ione (Jennifer Rubin), an Amazon leader, helps a young village girl who is seeking revenge on the Roman general who killed or enslaved her family. So bad it might explain why IMDb doesn’t show any subsequent credits for Jennifer Rubin. Aursra Juskaite was key makeup artist.
