Just finished watching a really good documentary about the Munich Olympic hostage situation. It's called One Day in September. It has mostly live footage, interviews some of the police and political figures involved, wives of some of the hostages, daughters of some hostages and even interviews one of the surviving terrorists.
I was only a few months old when it all happened so I didn't know the whole situation. I think that even if you remember all of it happening, you will still find it very good. Michael Douglas is the narrator.
I can't believe how bad they botched the whole situation. Even what happened later, which I think is the subject of the movie Munich by Spielberg.
