At the beginning of the film, Aunt Jessie takes puts two spoonfuls of sugar in her coffee, then puts the spoon down on her saucer. But in the next shot from behind her, she is seen putting a third spoonful of sugar in her coffee, replacing the spoon in the sugar bowl, and picking up another spoon to stir her cup.
When Emil appears in his Nazi uniform, the shirt and pants are those of the Hitler Youth (which is appropriate for someone his age). However, the armband is not that of the Hitler Youth (alternating red and white bands with a swastika inside a white diamond), but that of a regular party member (solid red background with a swastika in a white circle). He would not have been eligible for full party membership - and the party armband - until his 18th birthday.
