Into the second half of the movie, when the Inn is shown from the outside, the chimney and metal pipe stack suddenly disappear and are replaced with a smoking brick chimney. Sometimes during the movie, the chimney is missing entirely, but the roof is smoking.
The movie takes place in the mid of December just before Christmas, and yet, only time you see winter is on stock footage - bare deciduous trees and a lot of snow. In reality, it was obviously shot in the summer - there are a lot of green deciduous trees and bushes especially in the downtown. In the majority of outdoor scenes can be heard loud bird singing, and singing birds don't sing in autumn and winter.
