Saw March of the Penguins recently. I was vaguely aware of the arduous incubation process for emperor penguins, but this was both educational and absorbing. I didn’t realize how arduous it is, and how much the odds are stacked against successful reproduction.

The narration toned down the harshness–the death–for the benefit of the peanut gallery, but the viewers get the idea.

Also interesting to contemplate was the making of the documentary. How the hell do you sit around in -60° weather, through the monthslong night, to film a bunch of penguins without A) your equipment breaking; B) losing any toes; or C) going insane?
