On Tuesday evening, scenes were filmed outside an empty premises at number 5 Colliergate, which had been transformed into a miniature model shop, with table salt used to create the effect of snow.
Despite the rain, dozens of people gathered to watch the filming take place, at various points of the evening.
Rosa Burns, 23, was among those who stopped to look, describing it as “fascinating”.
“I actually saw them do a take, about four or five times. Everyone had to be silent in the street and nobody could walk past,” she said.
