When Otho is going through the house suggesting changes he is wearing white sneakers in one room and red ones in the next.

When Adam, Barbara and Juno ascend a staircase, talking about how Adam and Barbara should start more simply if they want to scare the Deitz family out of their home, there are two tape markers - a yellow and a blue one, very clearly on one of the steps.

When Adam creates the door to gain access to the spiritual world, he draws the outline and door knob quite visibly with chalk. Yet when the door is closing after they have gone through it, though you can still see the outline of the door, the door knob has mysteriously vanished.

During the dinner party, in one shot from behind we see Otho has very little wine in his glass, but in the following shot of him from in front, his glass is now nearly full. Nobody refilled it between the shots.

When Delia spray paints the word “mauve” on the wall, between shots it is apparent that the script of the word changes. One example would be that in the first shot the tops of the letter “M” are pointed, like triangle tips, but in the next they are more rounder. The writing also moves lower on the wall.

When Barbara tries to leave the house and falls into the sandworm's world you can clearly see her knee pads.

After Adam has drawn the chalk door on the wall, he walks forward and closes the “Handbook for the Recently Deceased.” In the next shot, as he knocks on the chalk door three times, the handbook is now open. In the next shot as he steps back, the handbook is now closed again.
