Winged Migration
I saw this movie yesterday... very very good documentary about migratory birds. Yeah, it's a documentary about birds. GO SEE IT! It's full of amazing images of birds in all kinds of different locales around the world and really makes you look at birds in a different way. It's well worth seeing on the big screen, unlike most of the crap out there. I'd venture to say it's better than League of Extraordinary Gentlemen, even.
I saw Pirates of the Caribbean and that was OK too, but it's no beautiful bird movie.
