Deliberate mistake: When Arthur follows Guinevere to the meeting with Merlin, her and the trees' shadows point at the viewer. Only Arthur has two shadows, one points to the left. The source of the moonlight is below the next ridge, and it's bright like a floodlight. Later, when Arthur is talking to Merlin, his face is always illuminated, even after a 180°-turn. (00:59:00)
Deliberate mistake: When the horses shy to get their masters back to Arthur's aid you can see Bors pull the reins to provoke that action. (01:28:35)
Deliberate mistake: From outside, the dungeon where Arthur finds Guinevere has no windows. When the knights force themselves in, it is pitch dark. But in some scenes a window is to be seen in the background, although the jails are one floor down. Even better the cages, in which among others Lucan sits: they are lighted from below. (00:46:20)
Answer: At the beginning of the film, we learn that young Sarmatians were drafted into the Roman military for a period of fifteen years. As the Romans lead young Lancelot away from his family, his father yells 'Rus!', the war-cry that is repeated throughout the film. 'Sarmatian' was the name the Romans gave the Rus, descendants of Norsemen who had settled in lands that still bear their name today: the River Rus (in modern Romania), Russia, Belarus, and Ruthenia. Culturally and geographically, these people were the Rus. So when they were inducted into the Roman army, their war cry of 'Rus!' identified them as being fearsome Rus/Sarmatian warriors, warned their opponents that the Rus were coming for them, celebrated their cultural identity, and symbolized their hope of returning home to the Rus. In the film Arthur honors them by yelling it back, signifying the unusual bond between leader and soldier exemplified in the Round Table, Arthur's respect for the Rus warriors, and his commitment to the idea that all men are born free and have the right to their own lives and beliefs.
Rus were a people combined of Vikings traveling between Denmark and Byzantium, and Slavic people. Sarmatians were before that, but from the same area and did intermingle with Slavs, so their blood is more than likely in there.
Rus was not from Denmark.
RUS is the word for Vikings who ruled the city of Kyev, and by the Ryrik family which assembled many Slavic tribes into "Kyev Rus", which is the name of state and foundation of modern Russia. Russia" as a ethnonim is similar to Rus but is not. Russian call themselves "I am Rus, I am ruski", and their language "ruski", but their country is "Russia" and they are RussiaNS, old name coresponding to Latin word "Ratio" (sense, mind) Race -of people...Sarmatians are Serbs, Serbs are Slavs and old Russians.
Ruthenia was the Roman name for what is now Ukraine. The main part of Rus i.e. Kyivan Rus is actually the land and people who are now known as Ukrainians. The Sarmatians were our ancestors.
