The production's schedule was set for a shoot in summer. In fact: on and around the longest day of the year, scenes were planned that would ideally require the longest night. Apart from that, the director and creative crew sought a specific look and feel in atmosphere in which mist would be ever present throughout the exterior scenes. Together with outspoken production design, requiring control to create more subtle, understating Christmas decorations, all seemed to point to shooting in a controllable environment that virtual production (or ICVFX) could provide.
Set in the picturesque village of Marken, occupying a peninsula on a lake (and therefore has a lighthouse), also has characteristic wooden houses that adds to the dreamy atmosphere of the episode.
To allow the crew control over the necessary factors mentioned before, the decision was made to create a virtual version of the village's centre. Having a responsive, real-time Unreal scene of the actual location, meant the dop could still make dynamic (hand-held) shots and last-minute adjustments to light and other elements that define the final result in-camera.
