Without giving too much away, "Crocodile" centers around a woman coming to grips with a troubling event in her past, and going to rather, uh, extreme lengths to keep a long-buried dark secret from seeing the light of day. The story is grim and upsetting, but the episode is nonetheless visually stunning and beautiful thanks to a breathtaking backdrop of both snow-capped terrain and ultramodern architecture. Naturally, it got people wondering where the Black Mirror team shot it. If you guessed Iceland, you win the prize.
Per BM producer Annabel Jones, the Nordic island nation provided the ideal landscape to tell the story. As she told the Independent "Crocodile is a beautiful, more personal study. It’s set in Iceland which introduced a totally new palette – one of the privileges of doing Black Mirror is the opportunity to create different worlds and moods and tones."
However, it wasn't the smoothest of shoots, according to the episode's director, John Hillcoat. In an interview with Small Screen he recounted that filming had to be suspended due to a huge snowstorm and the crew resorted to melting ice with boiling water in order to keep the shoot going. “It’s very humbling because it’s a constant reminder of how powerful nature is. It adds energy. The world is right in front of you, and you have to deal with it," he said.
