When Tony and Alois get splashed with water on their trip down the river, some of the water gets on the camera lens.
When Thomas is talking to Tony outside his new mansion, he points to the Big Dipper, which is both high in the sky and oriented "bowl-up". They would have to be very near the North Pole to see this. In Germany, the Dipper is only 20-25 degrees above the horizon when "bowl-up".
