Over the past couple of years, there's been a number of interesting documentaries out there - so many that some invariably slip through the cracks.
Here's a review I just ran into at Counterpunch.org of "Sir! No Sir!", an award-winning documentary about the GI protest movement against the Vietnam War. At the official site, you can order it on DVD and they are also running a program where you can donate to send copies free of charge to current active duty military personnel.
The documentary includes footage from Jane Fonda and Donald Sutherland's infamous "FTA" shows that were compiled into a feature film (and have never been released on video).
