From producer Jerry Bruckheimer comes an epic tale of one man's destiny to become a king. Clive Owen, is 'Artorius' or Arthur, the hero of Roman and British parentage eulogized in the ancient Celtic poem. Like his loyal Knights, he sees only chaos and devastation will follow Rome's final pullout of Britain. Although, as a dedicated Christian he is desperate to return to Rome to influence the budding religion, his first loyalty is to his pagan Knights. Arthur sees his duty is to free them from their servitude to Rome so they may return to their ancestral homeland in Sarmatia. However, before he can, he must lead his Knights of the Round Table on one last mission, deep into enemy territory on a quest of adventure and profound enlightenment.

Owen is perhaps miscast in this role, but it is worth seeing for the battle scenes.

Training Day director, Antoine Fuqua, and Gladiator screenwriter David Franzoni, set out to capture the unromantic elements of what they say is the true Arthurian tale. And they do depict a gritty world where battles were frequent and bloody. Clive Owen's King Arthur, doesn't have the screen magnetism needed for the role of this noble knight and he looks uncomfortable during his frequent monologues on personal freedom. But the film makes an adequate attempt at debunking the myth that 5th Century Briton and its knights were a chivalrous lot.To me, it's the legend that makes Arthur interesting - the stuff that's been laid down in fiction, not this ambiguous, formulaic plot.
