Messenger, The :The Story of Joan of Arc - Bad Camera Shadow
In the scene where Joan (Milla Jovovich) is riding on a horse, rallying the guys to help her fight, she rides across the screen from right to left during which avery good shot of the camera guy and his huge cam can be seen on the side of her horse. Seems to me they could have edited that one, it's so obvious and out of place.
There's another mistake of the exact same type in the same movie. At 27:55, when we see 4 horsemen entering the city from left to right (the four being Joan), we can see a camera/cameraman's shadow on her clothes.
