There is almost no usable footage of Sadr City in 2005. What exists is helmet-cam, news pool, and a handful of stills. Everything this film needs to show — the water tanks, the night rooms, the loudspeaker truck in an empty street, the Starship corridor — was never filmed by anyone.
The reconstruction register exists to show those things. It is not a substitute for archive and it never pretends to be archive. Its look is the label: the audience should be able to tell, from one frame with the sound off, that they are inside a memory rather than a record.
That distinction is the film’s credibility, and credibility is the whole subject of the film. It also happens to be the only reason this story can be made at a budget anyone will fund.
