After Gomez takes the picture, the black smudges on his and Morticia's faces change between shots.
When Gomez and Morticia talk in the conservatory, the sash on Gomez's robe is knotted toward his left. When they go into the living room to talk to Wednesday, it is centered.
In the opening scene were Gomez is standing on his head, a wire is visible on his right leg to help John Astin stay upright.
