King Arthur (2004)

Factual error: I normally wouldn't bother with this sort of nitpicking, but this film specifically claims to be historically researched - and it's full of historical blunders. For a start, the film is set as the Empire withdraws its last troops from Britain - which was in 407 AD. Now Artorius Castus was a real Roman officer who really did command Sarmatian foederati at Hadrian's Wall, but he died around 200 AD. Cerdic was a real Saxon warlord who did go raiding the Britons with his son Cynric, but he did this in the early 500s. Pelagius really was tried for heresy, but he was acquitted and died of old age; the trial was a decade after this setting, and in the fifth century you couldn't be executed for heresy anyway. Also in the fifth century the Pope had no authority over Imperial troops. I could go on and on but that will do for now.

Arthur: Pelagius told me once: "There is no worse death than the end of hope."
Guinevere: You and I are not the polite people that live in poems. We are blessed and cursed by our times.

Trivia: One thing was digitally edited for the promotional posters (the trio of pictures of Guinevere, Lancelot and Arthur): Keira Knightly's (Guinevere) bust was increased purely to attract more viewers.

Question: What breed of horses are used for Arthur and his knights? It looks like Galahad is using a different breed of horse than everyone else.
