Continuity: When Dorothy looks up and spots the head of the ‘Gump’ on the wall, it is covered with cobwebs. Later when Jack removes it for the couch, it is clean.

Visible crew/equipment: As the camera is panning around to show off the variety of heads Mombi has collected, in one shot you can see the reflection of the cameraman with a camera in one of the glass screens.

Continuity: Dorothy and Ozma escape the clinic after the power goes out. However, as they're running outside the clinic, you can see that the lights are on inside.

Other: Nurse Wilson puts Dorothy into a room with a bed. After she says "You may have a nap if you wish," she leaves. Dorothy looks around the room for a while and when Dorothy looks out the door, Nurse Wilson has just gotten to the end of the hall. The hall is not very long and Nurse Wilson is not walking at a slow enough pace to have just reached the end of the hall. She should have already gotten past the end of the hall when Dorothy looks out.
