Near the end of the movie, Everett is sitting in the early 50's GMC pickup. Showing in the bed is a spare tire of 1980 up vintage.
The paint "tins" that Maudie is using look like modern aluminum pull-tab type containers not old sardine tin cans.
Despite the fact when in the hospital near the film's end, the year is 1970, there are shots of a modern doorknob, folder holder on the wall, and automatic door sensor.
