Continuity mistake: Throughout the movie Astrid's eyebrows change colour from a light brown to a dark brown.
Continuity mistake: When Astrid and Claire visit Ingrid in prison, two kids are seen running towards them from behind. Before the camera angle changes from facing Astrid, both kids are still behind her. However, when it shows the backside of Claire and Ingrid in the next shot, the two kids have already passed all three of them. (01:06:25)
