King Arthur

In the 5th century AD, Clive Owen stars as Arthur, a Roman officer, who leads his group of Sarmatian knights and half-British Roman commander Artorius Castus in a mission to evacuate an important Roman family from north of Hadrian's Wall. They must defeat an advancing army of invading Saxons led by Cerdic and his son, Cynric. Along the way, Arthur meets Guinevere (Keira Knightley), marries her, and becomes King of the Britons after defeating the Saxons in the Battle of Badon Hill.
