When Haghi gives Dr Matsumoto's information to his spy, she is wearing dark nail varnish in the close-up of the card in her hand. Her nails are not polished in the other shots of the scene.
It seems odd that Haghi, a man "richer than Ford" and who enthusiastically adopts new technologies judging by his office equipment, hand rolls his own cigarettes when commercially manufactured ones had been available for decades.
When Sonya and Franz (the chauffeur) are tied up and trying to escape, the hand cranking the camera is visible.
