Revealing mistake: When Will Scarlet finds the injured Much in Sherwood Forest about three quarters of the way through the movie, a white vehicle can be seen travelling from right to left in the background. (01:27:40)
Plot hole: When Iris Henderson and her two friends arrive at the hotel, Iris orders dinner and asks that it be sent up to "our" room. The waiter arrives when the three are changing. But later, when it's time for bed, Iris says good night to her friends, who leave her alone in the room (as she must be for the sake of subsequent developments).
Continuity mistake: In one of the early scenes where Baby, the pet leopard is introduced, you can tell that the scene was shot twice and overlapped. Baby's leash has an obvious gap in it, and the two halves move independently.
Continuity mistake: When Jimmy Stewart is talking to his girlfriend, he gives her a flower, and at different points in the conversation, she has it over her shoulder, or on her lap, depending on the angle of the shot.
Continuity mistake: Mr. Kilbourne sits at the breakfast table and asks for his newspaper; during the scene the tea strainer to his right is facing upwards in the wider shots, and pointed with the opening down on the table in the close-ups. (00:04:30)
Suggested correction: No car, just light on the hilt of Scarlett's sword.
I verified the scene. It's definitely not from the light of Scarlett's sword. It occurs after Will gets off his horse and the horse is turning. To the right of the horse is a tree in the background. To the right of that is a small clearing, about level with the horse's mouth. For a fraction of a second you can see a white object go across the small clearing in the same manner as a white car driving by.
