Since Earth, the first Disneynature film, released a decade ago, the independent Disney unit usually puts out something new each Earth Day. The publicists are happy to boast that of the eight top grossing theatrically released nature docs, seven are theirs. (Nothing's every going to catch 2005's lightning-in-a-bottle juggernaut March of the Penguins.) A portion of the first week's receipts are forwarded to an environmental charity, which means you can feel good about driving to the theater instead of taking the bus. Other releases have gone straight to streaming or, in the ancient days of a decade ago, home video.
For some reason, the team nixed the Natalie Portman-narrated Dolphins last year, only a week before its release. (A version was released in France under the name Blue.) As such I've never seen it, but I've gobbled-up everything else they've put out. (But alllow me to give a shout-out to the greatest theatrically-released nature doc of my life, Claude Nuridsany and Marie Pérennou's insectophilic Microcosmos.)
Disneynature's latest is Penguins, narrated by Ed Helms and co-directed by Disneynature mainstay Alastair Fothergill with Jeff Wilson. It's absolutely adorable (because it's about penguins!) and features needle-drops by both REO Speedwagon and Whitesnake. But where does it fit in with the rest of the series? Grab some extra camera batteries, put on some all-weather gear and let's hike through the ranking.
