This is a documentary I watched a few years ago, and which I found both inspirational and interesting. It was made by an Irish-American comedian, Des Bishop, who went to live in the Gaeltacht for a year to learn Irish. The documentary was originally aired in 5 parts, but I found the full documentary on Youtube as a single video.
