King Arthur (2004) is a historical adventure film directed by Antoine Fuqua. The movie offers a gritty and realistic take on the legendary tale of King Arthur, reimagining the well-known myths as a story rooted in historical events during the fall of the Roman Empire.

Clive Owen stars as Arthur, a Roman officer of Sarmatian descent who leads a group of loyal knights, including Lancelot (Ioan Gruffudd), Galahad (Hugh Dancy), and Bors (Ray Winstone). These knights are bound by a lifelong oath to serve the Roman Empire but long for freedom. As the Roman Empire withdraws from Britain, Arthur and his knights are tasked with one final mission: to rescue a Roman family from a village threatened by the advancing Saxon army, led by the brutal warlord Cerdic (Stellan Skarsgård) and his son Cynric (Til Schweiger).

Along the way, Arthur encounters Guinevere (Keira Knightley), a Celtic warrior and leader of the Woads, a native British tribe fighting against the Saxons. Guinevere and her people inspire Arthur to embrace his destiny not as a Roman soldier, but as a leader who will unite the Britons to fight for their own freedom against the Saxon invaders.

King Arthur is known for its more grounded and realistic depiction of the Arthurian legend, stripping away much of the fantasy elements traditionally associated with the story. The film emphasizes themes of honor, duty, and leadership while presenting intense battle scenes and a portrayal of a Britain on the brink of transformation. Despite mixed reviews, it is appreciated for its strong performances, particularly by Clive Owen and Keira Knightley, and its unique take on the legendary figure of King Arthur.
