Factual error: The story takes place in the Pacific Northwest (Vancouver) in November and December. Washington may be known as the "Evergreen State", but there are still numerous deciduous trees - and deciduous trees have leaves that change color in Autumn (yellow, orange, red) and then shed (fall off), not stay green through December or into the new year.
Continuity mistake: Compared to the original location of the lamp when Vann entered the bar, none of the shots showing a portion of the lampshade would be accurate. The close-ups of Casper show a portion of the lampshade too close and at the wrong angle. When the camera shows front views of Casper and Vann, the lamp should be visible but is not. A back view of Casper shows part of the lampshade to her left, but doesn't fit where it was located before this. Likewise, a side view of the bartender does not include the lampshade. A later shot of the bartender shows a portion of the lampshade and part of the jar of pickles, which is now in front of him, up too high, and can't be on the edge of the bar. In an apparent attempt to use the lampshade for continuity, it was used way too much and rarely, if ever, at the right angle, height, and position. (00:04:16 - 00:05:50)
Continuity mistake: When Vann enters the bar, his view shows the bowling pin tap near the center of the bar, with the jar of pickles behind it centered on the bar, and a lampshade some distance past the bartender (or possibly on the innermost edge of the bar). When Vann is walking along the bar before he sits near the far end, the pickle jar is now touching the outer edge of the bar close to Casper's elbow resting on the bar, and the lamp is on the bar close to the bartender. (00:04:05)
Continuity mistake: The camera goes back and forth between Vann and Ferrin when they are having a conversation in the post office. Ferrin's hair is very frizzy the whole way around her face (and a total mess). There are some strands of hair that dangle from her scalp which aren't always the same. Perhaps more noticeable is a clump of hair on the left side of her head that intermittently sticks out sideways a few inches. When there is finally a rear view of her head, Ferrin's hair is suddenly neatly combed back in a bun with little or no frizz - only the strands that dangle in the front stay the same. (01:18:50 - 01:19:36)
Continuity mistake: The entire bar scene at the beginning of the movie contains numerous continuity errors for the props (e.g, lamp, jar of pickles) and background. The background changes and it is difficult to see what is being shown. In some views, there appear to be some kind of pillars or wooden rails/posts that are practically up to the bar and/or above Casper's head. At times, the ceiling looks domed with pictures arched/curved from the top of the wall to the domed ceiling. There is an overall lack of continuity in the bar scene.
Continuity mistake: The entrance door to the bar, which Vann closed behind him, is ajar when it can be seen. (No one else came into the bar or left while Vann was there). (00:04:04 - 00:04:41)
