I'm only just now getting around to seeing this good nature documentary about how emperor penguins carry out their lives in Antarctica. (If you haven't seen it: a lot of walking is involved.)
The film's makers do a bang-up job of staying out of the picture. It's easy to guess that they were a lot less comfortable than the penguins during the shoot. (At least they weren't menaced by seals and albatrosses.) I imagine they were tempted to compare the penguins' hardships with their own; they let the opportunity pass, fortunately.
However, it is just a nature documentary. Geez, it's not like it's Citizen Kane or anything.
