The movie presents a picture that laird is some kind of Scottish nobility and is a feudal owner in village which is nothing more than an internet meme. There is no feudalism in Scotland, and laird wasn't nobility title ever as the lowest nobility title is a baron which is above laird who is just a owner of a large, long-established Scottish estate.
The movie takes place just before Christmas, and it was shot in the winter. However, there is a small difference between mid December and late February / early March - you can hear loud singing by singing birds in the few outdoor scenes, and they don't sing between early autumn and late February / early March.
