At about 15:00 an exterior shot of the "hotel" in Antwerp is obviously a still photograph: the name of the hotel on the facade is reversed; the negative was flipped.
Antwerp is located in Flanders, the northern part of Belgium. The primary language spoken in Antwerp would therefore be Dutch (more precisely Flemish, the Belgian dialect of Dutch) and not French (or more precisely Walloon, the Belgian dialect of French).
