The man Joel is talking to on the plane in the very first scene is actor John Aylward, who would go on to have a recurring role on this series as pilot Charles "Red" Murphy, starting with episode #5, "The Russian Flu".
Elaine Miles won the part of Marilyn Whirlwind by accident. She accompanied her mother, who was auditioning for the part of Marilyn, and they cast Elaine instead.
In this episode we discover that Holling is Mayor of Cicely, Maggie has a trick knee and Maurice grew up in Oklahoma City.
Continuity error: In alternating shots during the town meeting scene, Holling switches between sitting behind Maurice, facing the collected townspeople, and sitting next to Shelly, facing Maurice.
In the scene where Joel and Maggie are pouring the wine, Maggie's hair changes from scene to scene.
When Ed approaches Holling and Shelly's tent, he knocks. It has been established in all episodes so far that Ed never knocks, just enters, as Indians think knocking is rude.
When Maurice passes the biscuits to Chris as they're having dinner, a fishing line is clearly visible pulling the plate down the long table.
Ed mispronounces the town of Sleetmute by saying the last syllable as 'mutt' instead of 'mute'. Sleetmute is an actual town, located on the Kuskokwim River, 243 miles west of Anchorage.
Dave mispronounces Tlingit as 'tuh-LING-it' instead of its correct pronunciation, which sounds similar to 'KLINK-it'.
When describing his brother, Joel describes his brother having a "Golden Mogan David", however when we see Jules, he doesn't have one.
In a scene where Maurice and Holling are on the horses headed to pick up Bill, Maurice has a black eye and Holling has a bloody nose, but they hadn't gotten to the bar where they had gotten into a fight yet.
Some of the final close-up images of the group photo at Joel's party do not match the whole photograph which is seen at the beginning of the scene. For instance Joel and Maggie are next to each other in the close-up, but noticeably apart on the photo.
When Joel is talking with Eve in his office about her condition, he takes off his glasses; the camera shifts to Eve for her lines and then back to Joel, who takes off his glasses again.
Goof: When Maggie is throwing things at Joel at her house, a cassette tape hits him between the eyes. Later on he tells her he would have lost an eye if it hit him "an inch to the left." But for the rest of the episode he is wearing a band-aid on his right temple, to the wrong side of his eye.
Goof: At the end of the episode, Chris talks to the town about "the last few days" in the dead of night. In Alaska following the solstice, there are a few weeks with only twilight or a few minutes of darkness before a regular day-night cycle resumes.
Goof: When Chris dreams he is in the "Last Supper Club," he is introduced to the Apostles. Four of them are called Matthew, Mark, Luke, and John. While these are the four Gospel authors, Mark and Luke were not Apostles, and therefore were not present at the last supper. (They were disciples of Jesus, but not called specifically by him.)
When talking with Joel at the Brick, Bernard takes his hands off the counter twice. Once when he is shot from behind and, for the second time, immediately after that, when he is shown sitting in front of the camera.
When Marilyn and the piano tuner are playing together at the end of the episode, there are three elementary-school age children sitting at the front tables. This marks one of the very few times that children have ever been seen in Cicely.
About 14 minutes into the episode when Jeff Flemming arrives at the O'Connell house while Joel is in the living room chatting with people, the door bell sounds exactly like the good old NBC chime. Northern Exposure aired on CBS!
Goof: Maurice says his grandfather got the house in 1918, his father was born there, and then he was born there "twenty years later." However, that would make Maurice born in 1938, and he would have been far too young to fight in Korea in 1951.
