Centurion is a 2010 British historical action-war film directed by Neil Marshall, loosely based on the legend of the massacre of the Ninth Legion in Caledonia in the early second century AD. The film stars Michael Fassbender, Olga Kurylenko, Dominic West and Liam Cunningham. Beginning in 117 AD, the narrative opens with a Roman soldier fleeing across a snowy landscape, saying; "My name is Quintus Dias. I am a soldier of Rome, and this is neither the beginning, nor the end of my story." The Romans have been unable to fully conquer the British Isles, meeting the fiercest resistance in the north, and the Picts of Alba are engaging in a guerrilla campaign against the Roman forts along the Glenblocker line and the Gask Ridge at the southern border of the Scottish Highlands. At Pinnata Castra, the Picts ambush and destroy the entire garrison, taking only one survivor for questioning, the centurion Quintus Dias, because Dias can speak the Pictish tongue. Taken prisoner by Vortix, Dias is brought to the Pict king Gorlacon who has united the northern tribes; Dias is brutally interrogated in the presence of the leader's son, who is forced to watch.
