Anachronisms: Modern cars are visible during the car journey from the hospital.
Factual errors: Somehow the two brothers have completly different accents. Ingemar speaks Swedish with a Göteborg-accent, while his brother Erik speaks a strong Stockholm dialect.
Factual errors: Gunnar is supposed to be from Småland, yet he speaks with a strong Göteborg accent. Both of these are "Geatish dialects" (Götamål) however the dialect of Göteborg differs enough from that of Småland that it is jarring to those who are familiar with Swedish dialects.
Crew or equipment visible: A part of the helicopter can be seen while Ingmar is sitting on the train down to his uncle for the second time
Audio/visual unsynchronized: Sound editing: When Ingemar's walking next to the river kicking metal drums, two of the drums are very different in appearance, but give off exactly the same sound.
Continuity: At the very end, the uncle is trying to fix the door. When he turns to go in the house, he leaves the door open, but in the next cut the door is closed.
