“Tides” (alternative title “The Colony”) is a sci-fi movie from 2021 about a post-apocalyptic world at the moment the first human communities are about to re-settle again. The only territory suitable is a coastal strip that is covered by tides twice a day. The area is a tidal zone, not quite land and not quite sea, with little to no vegetation and natural shelter for the people to build a more permanent habitat.
The landscape and weather in the story are the same as on the location, the movie was filmed. “Tides” was largely filmed outdoors on the small island Neuwerk in the German Tidelands, situated between the estuaries of the rivers Weser and Elbe.
Director Tim Fehlbaum explained in an interview how this landscape inspired the movie plot in the first place:
“For the outdoor scenes we went to the German Tidelands, which was where the idea for the film started. I’m a very visual director and my ideas often have a visual trigger. I had never been to the Tidelands and having grown up in the Swiss mountains being at the low point of Germany was eye-opening. Looking out at this expanse of water was so interesting because in an hour or so, everything you just saw becomes covered in water. The floods in the film are real, and they come in twice a day. Shooting there was exceedingly difficult because we could never shoot much longer than two or three hours, and I always wanted to keep shooting, but it becomes a question of minutes before the water is at your knees and suddenly up to your chest.”
You could say, the movie is really an exploration of this landscape and the living conditions and the atmosphere in tidal zones. That human renewal after the partial retreat and ecological meltdown takes place in such a tidal zone is interesting as it references this landscape as a realm of opportunity, transition and change – a liminal space full of potential rather than decay.
This confirms what historian John Gillis wrote in 2012 in his study of The human shore: “The many votive offerings and burials that have been found in such places as England’s Witham Valley leave little doubt about the cultural generativity of places where land and water met. Wetlands were among the first terrains to be enculturated, transformed through ritual performances from undifferentiated nature into memorable sacred places. From the earliest times, ecotones produced not only a good but meaningful life.”
I find this inspirational in regard to our current situation of ecological and social transformation. Author Kim Stanley Robinson made a similar reference to the “intertidal” as a space of opportunity and renewal when sketching his “Super Venice” in the post-apocalyptic novel “New York 2140” four years earlier. It is striking how both works are set in tidal zones, how both interpret them as spaces of renewal, and yet how radically different they paint this landscape.
