Continuity mistake: After the wedding between Elizabeth and Phillip, the royal family walks to the Buckingham Palace balcony to greet the British citizens. Peter gives a lit cigarette to King George VI who takes a few puffs, hands it back to Peter, then walks toward the balcony. He stops for a moment, attempts to straighten his jacket and inadvertently pulls his tie down about half an inch, making it look disheveled. A few seconds later, the Queen Mother turns to help walk the king outside. Now, the king's tie is straightened up as it was about five seconds earlier. (00:17:35)
Factual error: When carolers enter the room, a teen girl with modern dental braces is shown. Dental braces of the time did not glue directly onto the teeth as they do today. (00:41:55)
