I recently saw "March of the Penguins": Excellent. Incidently it appears to have been shot by a French crew and there is a short out-takes section during the closing credits, showing some of the difficulties they faced while shooting it. Well done by all concerned.

I also just finished the National Geographic TV special on 9/11, which was also well done. As it moves to the conclusion over two nights, it clearly showed why the changes contained in the Patriot Act were so necessary, including the use of libraries and their computer access, which allowed the terrorists to pass messages, keyed on the books they took out, as well as claiming lost Passports to cleanse the passholder of previous visa stamps indicating prior entry into countries supporting terrorism. It also indicated how people could abuse the US system of asylum-seeking (which we have now tightened up on).
