Shoah (1985)

Lanzmann doesn't try to understand what happened; he just collects details. It's impossible to know just how horrible conditions really were, but listening to these stories of sights, sounds and smells can break your heart. Amazingly, the stories eventually begin to corroborate each other, and you begin to understand how, horrifically, these events came to actually happen.

The film runs 9-1/2 hours without a scrap of stock footage, and as off-putting as it may seem to sit down to watch it, the intensity and honesty of the pure storytelling soon draws you in. New Yorker's now out-of-print DVD collects the complete film, with English subtitles on four discs. It includes a director biography. In 2010, the film was re-released for its 25th anniversary.
