When Claude joins a wooden-sword fight while the Langmann family is living in Dijon, a flag containing a swastika is hanging from a building in the background (at 0:08:51 on the Cohen Film Collection BD; at 0:09:01 on the Criterion Collection DVD). Most viewers would assume that the only swastika flag allowed to be flown on dry land in German occupied France would be the German national flag (1920-1945) containing (on both sides) a right-facing swastika rotated to a 45 degree angle from vertical on a white circle in a red background. The flag shown in the film has a left facing swastika whose arms are aligned with vertical and horizontal.
