Going Upriver: The Long War of John Kerry, the biographical movie made by George Butler of Pumping Iron fame, is available for free -- and legal -- download.
This site offers links to downloads via FTP, EDonkey, and BitTorrent, with Kazaa "coming soon."
The movie has gotten good reviews from professional movie critics, and several Democratic partisans have written it up positively too, including Kevin Drum.
So, Go Upriver for it.
[EDIT to add: I'm using BitTorrent to download this file and I'm getting very fast speeds (for me). I rarely ever make it to 40kb down and now I'm getting over 70. If you have BitTorrent, I'd advise using it and keeping the torrent open for a long time after you download it.]
