Trivia, insights & behind the scenes
Netflix partnered with WWF, making this their most expensive documentary ever — and the first to explicitly frame every episode around climate change rather than treating it as sidebar.
The infamous walrus scene required producers to break their 'no intervention' rule; they filmed hundreds falling to their deaths from cliffs after sea ice loss forced them ashore.
