Continuity mistake: The locations of Helena's headbands/ties vary. She has a small, tightly-bound red hair band on the right side at eye level and a yellow one about mid-neck (plus several others). The red band (which looks orange at times) is a couple of inches lower when she sits to talk to Nikolaj. After she shakes hands with Nikolaj, the red tie is above her ear (and others do not appear to be present). (00:07:56 - 00:11:38)
Deliberate mistake: The ghost opens Nikolaj's bedroom door an inch or so, yet there is enough light emitting onto the hallway floor for the door to be open about halfway. After the door closes, the light on the floor continues to gradually fade towards the closed door. (00:17:05)
Visible crew/equipment: There is no light in the kitchen that can produce the light/glare in the upper right corners of Nikolaj's glasses when his mother is facing him from a couple of feet away. Also, there is glare on his glasses when he is standing in school, reading his essay, and sitting at his desk. (Lights from camera or equipment can explain the glare.) (00:03:37 - 00:06:04)
