Frozen Planet II and Blue Planet II are landmark natural history series and masterclasses in climate change storytelling. Via captivating sequences, charming characters and compelling stories, the viewer is deliberately drawn into a world that they can’t help but care about, before being told about the very serious threats facing it. Such powerful storytelling can have a big impact; Blue Planet II, for example, persuaded people across the world to give up single-use plastics. But how are these films made? Who crafts the stories? And how do you engage people in the climate emergency without freaking them out? At Wildscreen film festival in Bristol, host Isla sat down with film-makers Rachel Butler Scott and Yoland Bosiger, producers who have worked on both Frozen Planet II and Blue Planet II among many other series, to chat about filming in the most remote and hostile environments on earth, diving under sea ice, and connecting people to life under the waves.
