Centurion (2010)

Britain, 117 AD. A splinter group of Roman soldiers fight for their lives behind enemy lines after their legion is decimated in a devastating guerrilla attack. Tired of constant harassment by the Picts in Caledonia, the Romans send in their toughest legion, the Ninth. However, after things don’t exactly turn out as planned, the few survivors, led by Quintus Dias (Michael Fassbender), have to struggle back to the border before fierce, vengeful warrior Etain (Olga Kurylenko) wipes them all out.
