King Arthur is a legendary British leader who, according to medieval histories and romances, led the defence of Britain against the Saxon invaders in the early 6th century. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various histories, including those of Gildas, Nennius and the Annales Cambriae. Arthur's name also occurs in early poetic sources such as Y Gododdin.
Knights of the Round Table were those men awarded the highest order of Chivalry at the Court of King Arthur in the literary cycle the Matter of Britain. The table at which they met was created to have no head or foot, representing the equality of all the members. Different stories had different numbers of knights, ranging from only 12 to 150 or more. The Winchester Round Table, which dates from the 1270s, lists 25 names of knights.
Sir Thomas Malory describes the Knights' code of chivalry as:
To never do outrage nor murder
Always to flee treason
To by no means be cruel but to give mercy unto him who asks for mercy
To always do ladies, gentlewomen and widows succor
To never force ladies, gentlewomen or widows
Not to take up battles in wrongful quarrels for love or worldly goods

The legendary King Arthur as the center of the story and the medieval legend. These stories describe King Arthur's life, the adventures of his knights, and the adultery of his knight Lancelot and Arthur's queen Guinea.
This legend became popular in Wales in the ninth century A.D. and later in Europe through Jeffrey's literary works in Monmouth. Cretian de Trojan, Vas, Leiamen, Mallory and others have written stories about the Holy Grail. The theme of Victorian Age became popular again. The important writers were Tennyson's Pastoral of King Arthur and White's Past and Future Kings. Whether Arthur is a historical figure remains uncertain. Medieval legend says that he was a fighter of the 6th century who supported Christianity and led the British tribes to defeat the Saxon invaders. He died in the Battle of Kamanland around 539 and was buried in Glastonbury. See Galahad and Merlin.

　　影片的人物原形来自15世纪英国最富有传奇色彩的国王--勒?莫特?亚瑟。亚瑟王更多的感性认识来自神话传说，他和圆桌骑士的故事，已然是诠释基督教传承的文化传说。历史学家们对于亚瑟王的国籍和年代问题有很多争议。本片以历史学家托马斯?马洛里的文稿基础完成剧本，认为亚瑟王是罗马人，在英国立下赫赫战功，正是亚瑟的上台，才让英国打败日耳曼部落推翻罗马帝国的统治，最后赢得了革命性的胜利。　　我喜欢这部电影，喜欢里面七个骑士的对自由深切的渴望。这自由面前，生命都显得不那么的动人了。在现实生活中，我们在生活的网上爬行，到处都是束缚，却鲜有人对此斗争反抗。　　也许，我们这样生活了太久，已经意识不到了自由的美丽了。　　我自认为是个比较懒散的人，不太喜欢太多的规矩，怎么舒服就怎么过。最好，逍遥的像个桃下醉仙。显然，我是在做梦了。　　虽然，从影评界的角度来说，亚瑟王不能算是顶尖一流，但影片中骑士间超越生死的友谊，草原上大家对自由的呐喊，以及大雪中失去伙伴的悲痛，绝对能唤起人们心中的某些情愫。
