As far as the DVD extras go...
No commentary track (it's already a documentary with Moore's opinion... why add VO of the same)
The DVD 'Features' menu is ironically set with colour codes as "Mike's Homeland Security system".
1.78:1 anamorphic widescreen
English DD5.1 Surround
Featurette: The Release of Fahrenheit 9/11
The Cannes Jury (Tarantino and others) explains why
they awarded it the Palme d'Or.
(Not for political affinity, but for its own merits as a documentary on an important topic)
Montage: The People of Iraq on the Eve of Invasion
New Scene: Homeland Security, Miami Style
Outside Abu Ghraib Prison
The Montage is pre-war footage of families and cute kids all saying "we don't want war".
Unsurprising, and some might contest some folks didn't feel free to express themselves, but its hard to feel justified bombing and destabilizing a country if you'd seen any of that instead of drum-banging "WMD" and rah-rah spin first.
The Miami segment is about retired USCG vets boating around Miami spying on 'suspicious activity'.
Unarmed (thankfully), but it is spooky to think paranoid nosy seniors are encouraged
to report their neighbours in the interests of Homeland Security.
The Abu Ghraib crowd shots have some interpreter, some subtitle, but are mostly raw footage of a scheduled 'release' of 100 prisoners. It is clear that the soldiers are equally as concerned about cameras and unfiltered 'bad pr' (from the military view) as they are about getting shot by weapons. They'd clearly been instructed to confiscate film. Why
Eyewitness account from Samarra, Iraq
Some of the footage from the Samarra Raid is in the film, but this segment is longer and has interviews with the Swedish journalist (an actual journalist... points out where other media have failed and barely deserve to be called 'reporters') who shot the footage on the raid and has followed up since.
This is one of the best segments on the DVD as far as I was concerned.
Extended Interview: Moore with Abdul Henderson
Lila Lipscomb at the Washington D.C. Premiere
Marine Corporal Henderson is in the film handing out pamphlets and recruiting Congress' kids with MM. Some of his experiences in Iraq are detailed in this segment.
Lila is the Mom from Flint who appears often in the 2nd half of the film.
Arab-American Comedians - Their acts and experiences after 9/11
Condoleeza Rice's 9/11 Commission Testimony
Rose Garden press briefing after 9/11 Commission Appearance
The Comedians are sometimes funny, sometimes offstage just talking about how their lives changed.
Condi's footage is old news to anybody who paid attention at the time.
The President's brief comments are probably similarly familiar.
Each extra segment on the DVD has boards before and after with text details - usually just facts, sometimes more neutrally expressed than other times.
Worth watching with friends, I would think, if only because it makes you want to ask questions and discuss.
Definitely worth renting... worth buying if it matters to you, but I don't think avoiding it informs.
Even if you're hardcore opposed to Moore, some of the points raised are legitimate, most of the emotions are genuine, and the calls to participate in voting for your future ought to be energizing for either side.
