When Georgia is in the kitchen at breakfast time with Harlan and Rachel, she sits down at the table and sets down a plate with two well-cooked pancakes in front of her. In the following shots, the pancakes not only change position without Georgia touching them, but are now more lightly cooked.
On the first morning Rachel is in her grandmother's house, her grandmother is having her breakfast alone. The scene clearly shows a book with a blue picture on the cover kept on the corner of the table. Just then Rachel enters with the very same book in her hand and keeps it on the same spot.
The flowers in front of Georgia's home change. The first several scenes show her planting vibrant colors with many yellow and pink flowers. Later scenes only have pale purple flowers in front of the house.
When Rachel visits Georgia for the first time, she has rather worn off reddish nail polish. When she wakes up in the morning on the couch, obviously zoned out because of all the walking, without time to do much about her appearance, she has a professional looking French manicure. In the next scene she has red nail polish again.
In Simon's kitchen when he is playing his mandolin, the long shots show a note on the whiteboard near Simon's shoulder, a reminder to "call Fern about scheduling", with another note written in heavier black marker beneath it. In Simon's closeups the first note is clearly visible, but the second note is entirely absent.
The Idaho license plates on the vehicles in the film have an incorrect format. Standard Idaho license plates begin with a two digit number/letter combination identifying the county where the vehicle is registered (i.e. 1A - for Ada county, Boise area). The plates in the film do not use this format.
Rachel slides off her panties while trying to seduce Harlan, and when she offers to let him "touch it", she parts her legs slightly and it can clearly be seen that she's wearing another pair of panties.
in the scenes where it is raining you can clearly see the rays of the sunlight going through the trees and on buildings.
in several scenes when in Idaho the hills in the background are southern California hills.
In the "morning scene" after Rachel and her grandmother has had breakfast the shops are opening and one of the shopkeepers puts the "open" sign up facing inwards, the sign should have said "closed" when seen from that side of the door if the shop was open for business.
