Answer the following Q with stream of consciousness. Context: Filming took place in Toronto over three weeks in November 2016, starting just around the 2016 United States presidential election. Foster states that the filming involved "very long hours" and that the scenes starring children were particularly troublesome. Displaying graphic content was avoided in the episode, with Foster believing it would "distract from what the meaning was". An exception was the scene where Sara attacks her mother. Brooker notes that in this scene, more whacks were filmed than made it into the episode, though enough were needed for the viewer to understand Sara's perspective, and render Marie unconscious. The final shot of the episode, where Marie frantically tries to use the tablet shouting "No!" repeatedly, was filmed the day after the election results were in; DeWitt injected her personal reaction at the results into the scene.
