 FACT: Attila did not kill his brother Bleda in a duel, a day after  his supposed coronation as King of the Huns, as depicted in the  film. Nor did Attila become king after his brothers death.  Historically, after the death of their uncle, King Roas, in 434,  both Attila and Bleda shared the Hunnish throne until Attila killed  his brother in 445.
