Océans

It's important to note there are TWO versions of this film. Jacques Perrin's original runs 104 minutes and is narrated by Perrin in French. Disney bought the film, cut 20 minutes (much of it critical of human activity endangering the oceans and animal habitats), junked Perrin's spare narration, which lets you wonder at the sights on view, and substituted a gabby but emotionally chilly commentary by Pierce Brosnan.

Perrin's original version is not available in the US, per contract with Disney. The original is available in Europe on DVD and Blu-Ray (but unplayable on most US machines) but it seems to lack English subtitles. So you're pretty much stuck with Disney edition.

The original, however, is to my mind better and much more in line with Perrin's "Winged Migration" than the Disney version. The best that can be said for the US edition is that plays down the "humanizing" of animal life that was an annoy hallmark of Disney's True-Life Adventures of the 1950s.
