Factual error: King William IV died in the early hours of 20 June 1837, not 18 June 1837 as stated in the film with an on-screen caption. (00:36:06)
Factual error: Prince Albert was not really wounded in the assassination attempt depicted near the end of the film. Eyewitness accounts differed as to whether he pushed Victoria down to protect her or simply dived for cover himself, but neither of the two bullets fired struck either of them.
Factual error: There are heater panels at the bottom of the rooms, which didn't exist in that era.
