Revealing mistake: The film is set in 1997 the year of Diana's death. However there is a scene in where Tony Blair is being driven in a car and you can see a Mercedes through the rear window with an '02' number plate indicating a 2002 model vehicle.
Continuity mistake: After the Queen has made the changes to her tribute speech you can see she puts the cap back on her pen. The next shot she puts the cap on again. (01:20:25)
Continuity mistake: As the Queen is about to take the call from Tony Blair in the kitchen you can see in front of her a few plates of food and a chopping board with two cucumbers and a black handle knife. Near the end of the scene we see an overhead shot and there is only one cucumber and the knife has disappeared as well. (01:05:05 - 01:06:00)
Visible crew/equipment: After the Queen's jeep is stuck in the river, she glances around for a moment. The rigging of the lights and camera can be seen in the reflection of her glasses. Further, when she exits the car, the reflection of a man holding his hand to his chin can be seen in the door window. This must be a crew member, as in the next wide shot the Queen is completely alone. (00:59:50)
Continuity mistake: When Her Majesty drives into the river, there is no road to be be seen on the other side, and her car stops about mid-river. In the next shot, when walking from the car, she is very close to the bank on the other side, and in a following shot there is a road leading up from the stalled car.
