The front door to Tess and Stella's cabin opens in different directions depending on whether they are inside or outside. In exterior scenes, the door opens inwards to the left, and in interior shots, it opens inwards to the right.
Early in the film, Dan examines a "corpse," which is obviously breathing.
The scenes that encompass Jim's return to town and Lige proposing to Tess take place in the course of one night. Exterior scenes were obviously shot day for night, and some shots don't make any attempt to simulate nighttime. One of the most notable instances is when Jim and Stella go into the cabin to talk and the light outside is very bright (daylight). The front doorway is completely dark, however, when seen from the inside.
Although the story takes place in the stagecoach era of the 19th Century, all of Lois January's clothing and hairstyles are strictly in the 1936 mode.
In the opening scenes (c.2 minutes) a modern city can be seen in the background on two occasions.
The shadow of the microphone falls across Tess when she goes into the bedroom to take off her wrap, just before Lige proposes to her.
