While Grace is searching for the missing curtains, Anne and Nicholas argue while Anne draws. Her drawing goes back and forth, being less complete when the camera is beside her, and more complete when it is beside Nicholas.
Grace is teaching the children and tells them that they must study separately from their readers. Anne leaves to go into the music room and the door is locked but the camera stays with Nicholas in his room. He begins to read from his reader and the camera dollies around behind Nicholas and on the table you can see Anne's reader. In the next shot, Anne is in the music room with her reader.
When Grace is eagerly trying to conceal her children from the sunlight, she takes them to a room located in a narrow corridor decorated with pictures and a statue of the Virgin, near their bedroom. Grace opens the door into the room but, when we see out to the corridor from inside the room, the pictures are gone, the wallpaper has different pattern and color, and there is an electric lighting fixture on the wall not previously seen.
Grace says the house does not have electricity. However, when Anne is standing and reciting to her mother as punishment, the table to the left of Anne has a statue of a horse on it which is clearly backlit by the white light of an electric bulb. In the following shots as Anne and Grace argue about Anne's forgiveness, the light is gone.
Near the end of the movie when Anna and Nicholas are walking away from the house they are moving away from it and this is clarified by Anna's line "We're not at the end of the garden yet" but when they stand before the grave stones a few shots afterwards, the house is behind the graves. We know for earlier on when Grace has been talking to the gardener that the graves are near the end of the garden.
