Continuity mistake: On the morning of King George VI's death, the King's valet is in the dumbwaiter lift bringing up the King's tea and breakfast. Inside the lift shows the valet pulling the rope as it raises to the King's sleeping floor. The waiters are facing front and away from the valet, and the covered wall light is located closest to the main door with the rope in the left-rear corner. As the lift stops, the waiters are now facing the valet to the left, and the covered wall light is now located closest to the rear of the lift with the main rope now located in the left-front corner. These two scenes were filmed in two separate sets. (00:23:05)
Factual error: In the opening, a number of Lancaster bombers are flying over Windsor Castle, they did not come in to service until 1942. (00:00:20)
Factual error: Once the Queen has given Mr. Churchill his "dressing down", he simply turns to leave the room. However, he had not been dismissed. The Queen always pushes a button positioned on a side table to call her equerry who enters the room to escort guests out. With Mr. Churchill, she did not request her equerry. (00:54:00)
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: Peter Townsend wears the rank insignia of a group captain (and is referred to as Group Captain Townsend) from the beginning of the series in 1947. In fact, Townsend was promoted from wing commander to group captain on 1 January 1953. He was also appointed Commander of the Royal Victorian Order (CVO) in 1947, but is never seen wearing the appropriate medal ribbon, which should come first on his collection.
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)
