Big-budget action adventure based on the legend of King Arthur and the Knights of the Round Table. The film attempts to place King Arthur within the historical context of his time (around 500 AD), and take into account many more historical and political facts of the era than previous interpretations of the legend. It also dispenses with much of the magic and fantasy that have shrouded events of the period, although Merlin (Stephen Dillane) does feature as a shaman who used his powers against the Romans. Clive Owen stars as Arthur, who, as England falls into chaos after the fall of the Roman Empire, gathers around him a band of brave knights, including Lancelot (Ioan Gruffudd), Galahad (Hugh Dancy) and Gawain (Joel Edgerton), who hope to defeat the invading Saxon armies and restore peace and order to their country. Keira Knightley co-stars as Guinevere.
