At the beginning of the film, the table that Mahadev uses to write letters is covered with newspaper. After he starts talking to the man on the motorcycle, all of sudden, the table is magically covered with a plastic sheet.
At the very beginning, Mahadev is seen as brushing his teeth. Yet he was clean-shaven, a bit too clean-shaven for the time of the day and the village locale. He appears so, during most of the movie.
