Snagfilms - Documentary Library on the Web

What is it?  Snagfilms is an online library of documentary films.  Unlike youtube these are the complete versions of the film and you can simply filter what you are looking for through it's intuitive search filter on it's front page.  the films here are a bit of a mixed bag from mainstream productions to independent but it is possible to find a few diamonds in the rough.  You can 'Snag' a film too and watch it later if you like.

How can I use it in my teaching and learning?  Obviously this would be a great tool for high school subject teachers looking for content to engage their student and promote discussion.  Probably not a lot here for the juniors though.
