When Bill White is at the bar the first time, from one angle he appears to be drinking Leineinkugel's Honey Weiss beer. When they change angles, he is drinking some other brand. When they go back to the first angle, he's again drinking Leineinkugel's.
In Bill White's first bar scene, Glory's tray of shots switches from five shots to four, then back to five, throughout the scene.
When Bill White is sitting at the bar, contemplating whether to talk to Josie, the second button on his right sleeve is unbuttoned. When he gets up to go talk to her, he lifts his right arm, and his shirt sleeve is fully buttoned.
During the opening text about women miners, the word "Northern" is spelled "Norhtern".
One of the main elements of the film is that Hank is implacably opposed to Josey working in the mine until the vile treatment of her at the meeting leads to him supporting her. In real life, however, Lois Jenson (basis for Josey) and her father did not have this conflict; her dad supported her efforts to work at the mine because it was a good-paying job and would allow her to support her young son.
Lois Jenson, the woman Josie Aimes is based on, started working in the mines in 1975, but the film is set in the late 1980s. Josie's son's heavy metal t-shirts (Iron Maiden, Guns N' Roses) are accurate to the time period in the film, not the real life story.
When Bobby gets up from attacking Josie in the powder room, he runs up a ramp that appears to have water cascading down. He never splashes in the water or leaves footprints.
The indoor hockey scene was shot at the arena in Eveleth, MN, where the average temperature doesn't get far above 10 degrees Fahrenheit during hockey season. No one's breath is visible in the outdoor scenes, and the little girl holding onto the chain-link fence wouldn't do that without gloves.
The movie is set in 1988-89, yet it frequently shows the Clarence Thomas/Anita Hill hearings, which occurred in 1991.
The nets behind the cage above the glass at the hockey rink were not in use in 1989.
About 3/4 of the way through the film, a bottle of Tums Ultra is on Josey's kitchen table. Tums Ultra didn't exist in 1989.
Josie's truck is a 1990 or later.
When Josey drives through Minneapolis, a 2000 or later police squad car appears in the driver side window as she goes through an intersection. Squad cars
looked very different in the 1980s.
When Josey drives into Minneapolis, she is shown approaching downtown Minneapolis from the south. She should be approaching from the north.
