Other mistake: Two indoor sets which include large boulders, some brush and a painted backdrop are used in several episodes. Occasionally when someone walks by, the sound of his footsteps makes it obvious that a wooden platform is beneath the thin layer of dirt. Another set with a small cabin is used in several episodes and in each episode a different person lives in the cabin.
Continuity mistake: A watchmaker is riding in a horse-drawn buggy. The close-ups were obviously filmed on a studio set because the same shadows of tree branches pass across his body several times in quick succession.
