The bandage on Wallander's hand disappears a couple of times. When he is driving to the farm (when he finds the satchel) he wipes his left hand across his face and there is no bandage. When he is at the farm, the bandage is there. A second time, when he is driving away from his father's house, he again wipes his left hand across his face and the bandage is gone. Next scene, the bandage is back.
During the driving sequence following the incident with the unpaid pizza bill, a single closeup shot of Wallander behind the wheel of his car is flipped or reversed for no apparent reason, as if he was suddenly in a right-hand-drive Volvo, complete with the seat belt passing over his right shoulder instead of his left.
