In flashbacks, Henry VII describes the death and burial of Richard III on the battlefield at Bosworth. However, contemporary accounts of the battle state that the dead king's body was taken roughly 13 miles away to Leicester and buried under Greyfriars Church. This was confirmed in early 2013 when the skeletal remains discovered at the Church's former location the previous summer were positively identified by mitochondrial DNA.
When the court goes out a hunt Henry VII tells "The Boy" to shut up. While people used the expression to say someone had been locked away, held prisoner of quarantined back then the usage of the term shut up to mean stop talking didn't really begin until the beginning of the 20th century.
