Anglosaxon

The term "Anglo-Saxon" is from Greek writings going back to the time of King Alfred the Great, who seems to have frequently used the title rex Anglorum Saxonum or rex Angul-Saxonum (king of the English Saxons).
The Old English terms ænglisc and Angelcynn ("Angle-kin", gens Anglorum) when they are first attested had already lost their original sense of referring to the Angles to the exclusion ofthe Saxons, and in their earliest recorded sense refers to the nation of Germanic peoples who settled England in and after the 5th century.
The indigenous British people, who wrote in both Latin and Welsh, referred to these invaders as Saxones or Saeson - the latter is still used today in the Welsh word for 'English' people.
The term Angli Saxones seems to have first been used in continentalwriting nearly a century before Alfred's time by Paul the Deacon, historian of the Lombards, probably to distinguish the English Saxons from the continental Saxons.
There is a theory that the name of the Angles came from the Germanic and Indo-European root ang- = "narrow", i.e. "the people who live by the Narrow Water (i.e. the Schlei inlet)".

Architecture
Early Anglo-Saxon buildings inBritain were generally simple, constructed mainly using timber with thatch for roofing. Generally preferring not to settle in the old Roman cities, the Anglo-Saxons built small towns near their centers of agriculture. In each town, a main hall was in the centre.
There are few remains of Anglo-Saxon architecture, with no secular work remaining above ground. At least fifty churches are of Anglo-Saxonorigin, with many more claimed to be, although in some cases the Anglo-Saxon part is small and much-altered. All surviving churches, except one timber church, are built of stone or brick and in some cases show evidence of re-used Roman work.
The architectural character of Anglo-Saxon ecclesiastical buildings ranges from Coptic influenced architecture in the early period; basilica influencedRomanesque architecture; to in the later Anglo-Saxon period, an architecture characterized by pilaster-strips, blank arcading, baluster shafts and triangular headed openings.
In the movie, the type of houses were really different and also the fact that they do not lived near to centers of agriculture but it was similar that they have a main hall in the centre I think that the text that I found isbased in the early Anglo Saxon era.

Art
Anglo-Saxon art before roughly the time of Alfred (ruled 871–899) is mostly in varieties of the Hiberno-Saxon or Insular style, a fusion of Anglo-Saxon and Celtic techniques and motifs. The Sutton Hoo treasure is an exceptional survival of very early Anglo-Saxon metalwork and jewellery, from a royal grave of the early 7th century. The period between Alfredand the Norman Conquest, with the revival of the English economy and culture after the end of the Viking raids, saw a distinct Anglo-Saxon style in art, though one in touch with trends on the Continent.
Anglo-Saxon art is mainly known today through illuminated manuscripts, including the Benedictional of St. Æthelwold (British Library) and Leofric Missal (Oxford, Bodleian Library, MS Bodl, 579),masterpieces of the late "Winchester style", which drew on Hiberno-Saxon art, Carolingian art and Byzantine art for style and iconography, and combined both northern ornamental traditions with Mediterranean figural traditions. The Harley Psalter was a copy of the Carolingian Utrecht Psalter — which was a particular influence in creating an Anglo-Saxon style of very lively pen drawings.Manuscripts were far from the only Anglo-Saxon art form, but they have survived in much greater numbers than other types of object. Contemporaries in Europe regarded Anglo-Saxon goldsmithing and embroidery (Opus Anglicanum) as especially fine. Perhaps the best known piece of Anglo-Saxon art is the Bayeux Tapestry which was commissioned by a Norman patron from English artists working in the traditional...
