Visible crew/equipment: When Robert and Arvid are in the desert and Robert falls into the pit, you can see the shadow of director Jan Troell holding the camera.
Visible crew/equipment: In one of the first scenes, when Karl Oskar is taking the family to the new settlement, the boom mic is visible in the upper left corner for the entire shot.
Factual error: Ulrika is present at the communion in Karl Oskar and Kristina's home, even though she's a Baptist at this point. Not only would she not want to come, or even be welcome since she was now practicing a different form of Christianity, she would not need to come. Being married to the Baptist minister she would be attending communion on a regular basis.
