 Carpenters for the film were locals and young men from the United States, fleeing conscription into the Vietnam War; they were dressed in period costume and used tools of the period, so that they could go about their business in the background, while the plot advanced in the foreground.The crew ran buried hoses throughout the town, placed so they could create the appearance of rain.Since the city of Vancouver generally receives a great deal of rain, it was usually only necessary to turn on the hoses to make scenes shot on the rare days when it didn't rain, to match those shot on days when it did.
