Question: What 2017 documentary film imagines a journey by a person also known as Edith Swanneck?

full_context: Document 1: Ealdgyth, daughter of Earl Ælfgar: Ealdgyth ("fl. c". 1057–1066), also Aldgyth or in modern English, Edith, was a daughter of Ælfgar, Earl of Mercia, the wife of Gruffudd ap Llywelyn (d. 1063), ruler of all Wales, and later the wife and queen consort of Harold Godwineson, king of England in 1066. She was described by William of Jumièges as a considerable beauty.
Document 2: Ealhswith: Ealhswith or Ealswitha (died 5 December 902) was the wife of King Alfred the Great. Her father was a Mercian nobleman, Æthelred Mucel, Ealdorman of the Gaini, which is thought to be an old Mercian tribal group. Her mother was Eadburh, a member of the Mercian royal family, and according to the historian Cyril Hart she was a descendant of King Coenwulf of Mercia. She is commemorated as a saint in the Christian East and the West on July 20.
Document 3: Edith Walks: Edith Walks is a 2017 documentary film directed by Andrew Kötting which imagines a journey by Edith the Fair, wife of English king Harold Godwinson, from Waltham Abbey where he is buried to near the site of the Battle of Hastings and the invasion of England by William the Conqueror in 1066. It includes contributions from the writers Alan Moore and Iain Sinclair, the torch singer Claudia Barton, and the musician Jem Finer.
Document 4: Eleanor cross: The Eleanor crosses were a series of twelve lavishly decorated stone monuments topped with tall crosses, of which three survive nearly intact, in a line down part of the east of England. King Edward I had the crosses erected between 1291 and 1294 in memory of his wife Eleanor of Castile, marking the nightly resting-places along the route taken when her body was transported to London. Several artists worked on the crosses, as the "Expense Rolls" of the Crown show, with some of the work being divided between the main figures, sent from London, and the framework, made locally. "Alexander of Abingdon" and "William of Ireland", both of whom had worked at Westminster Abbey, were apparently the leading sculptors of figures.
Document 5: Ælfgar, Earl of Mercia: Ælfgar (died c. 1060) was the son of Leofric, Earl of Mercia, by his famous mother Godgifu (Lady Godiva). He succeeded to his father's title and responsibilities on the latter's death in 1057. He gained the additional title of Earl of East Anglia, but also was exiled for a time. Through the first marriage of his daughter he would become father-in-law of the Welsh king Gruffydd ap Llywelyn; a few years after his death, his daughter would become a widow and marry English King Harold.
Document 6: Edmund Ironside: Edmund II (died 30 November 1016), usually known as Edmund Ironside, was King of England from 23 April to 30 November 1016. He was the son of King Æthelred the Unready and his first wife, Ælfgifu of York. Edmund's reign was marred by a war he had inherited from his father, his cognomen "Ironside" was given to him "because of his valour" in resisting the Danish invasion led by Cnut the Great.
Document 7: Edward the Confessor: Edward the Confessor (Old English: "Ēadƿeard Andettere" ] , Latin: "Eduardus Confessor" ] ; c. 1003 – 5 January 1066), also known as Saint Edward the Confessor, was among the last Anglo-Saxon kings of England. Usually considered the last king of the House of Wessex, he ruled from 1042 to 1066.
Document 8: Azor (landowner): Azor was one of the most powerful English landowners at the time of Edward the Confessor in the 11th century. He was a kinsman and chamberlain of Brihtheah, a bishop of Worcester and a former abbot of Pershore. He owned property from Lincolnshire down to the Isle of Wight in many counties and like another great landowner of the times, Toki, he also owned urban property in addition to his vast possession of lavish country estates. He is mentioned in the Domesday Book and appears in countless histories of English counties along with his sons,
Document 9: Edith the Fair: Edith the Fair (Old English: "Ealdgȳð Swann hnesce" , "Edyth the Gentle Swan"; c. 1025 – c. 1086), also known as Edith Swanneck, was the first wife of King Harold Godwinson. "Swanneck" (or Swan-Neck) comes from the folk etymology which made her in Old English as "swann hnecca", "swan neck", which was actually most likely a corrupted form of "swann hnesce, ""Gentle Swan"" ". She is sometimes confused with Ealdgyth, daughter of Earl Ælfgar of Mercia, who was queen during Harold's reign.
Document 10: Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II. When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters. Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king. In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
Document 11: Emma of Normandy: Emma of Normandy (c. 985 – 6 March 1052) was a queen consort of England, Denmark and Norway. She was the daughter of Richard I, Duke of Normandy, and his second wife, Gunnora. Through her marriages to Æthelred the Unready (1002-1016) and Cnut the Great (1017-1035), she became the Queen Consort of England, Denmark, and Norway. She was the mother of three sons, Edward the Confessor, Alfred, and Harthacnut, as well as two daughters, Goda of England, and Gunhilda of Denmark. Even after her husbands' deaths Emma remained in the public eye, and continued to participate actively in politics. She is the central figure within the "Encomium Emmae Reginae", a critical source for the history of early 11th-century English politics. As Catherine Karkov notes, Emma is one of the most visually represented early medieval queens.
Document 12: Watling Street (book): Watling Street: Travels Through Britain and Its Ever-Present Past is the fifth book by the British journalist, novelist and cultural historian John Higgs. The book charts Higgs's journey along Watling Street, one of the oldest roads in Britain, from Dover to Anglesey, during which journey he records the so-called hidden history of this ancient path from its first creation up to the present day. As well as recording the historical figures and their stories surrounding the road, Higgs also meets up with and interviews contemporary figures along the way such as Alan Moore. The author describes the history of the road as, "Watling Street is a road of witches and ghosts, of queens and highwaymen, of history and myth, of Chaucer, Dickens and James Bond. Along this route Boudicca met her end, the battle of Bosworth changed royal history, Bletchley Park code breakers cracked Nazi transmissions and Capability Brown remodelled the English landscape.
Document 13: Adiva: Adiva was the first wife of Boleslaus II of Bohemia. It has been speculated that she was the progeny of Edward the Elder, King of England, and his second wife Aelfflaed, but the evidence for this is weak. Favouring the conjecture is the similarity of her name to certain Anglo-Saxon forms, and the introduction of English-influenced coinage into Bohemia. Nevertheless, since there are a handful of other possible candidates, the evidence for the hypothesis must be counted insufficient.
Document 14: Ealdgyth (floruit 1015–1016): Ealdgyth (circa 992 – after 1016), modern English Edith may have been the name of the wife of Sigeferth son of Earngrim, thegn of the Seven Burghs, and later of King Edmund Ironside. She was probably the mother of Edmund's sons Edward the Exile and Edmund Ætheling.
Document 15: Æthelred the Unready: Æthelred II, also dubbed the Unready (Old English: Æþelræd, ] ), (  966 – 23 April 1016) was King of the English (978–1013 and 1014–1016). He was the son of King Edgar the Peaceful and Queen Ælfthryth and was around 12 years old when his half-brother Edward the Martyr was murdered on 18 March 978. Although Æthelred was not personally suspected of participation, the murder was committed at Corfe Castle by his attendants, making it more difficult for the new king to rally the nation against the military raids by Danes, especially as the legend of St Edward the Martyr grew.
