A Esteticista (2005)

What starts out a standard talking head doc about one woman's experience in Auschwitz during WW2 turns into a picture of an aging Hungarian woman - Ms Emmy - and how having red hair saved her life. The filmmakers don't hide their involvement in the making of the film, rather are continually bossing her around, which allows us to appreciate the density, detail and focus of Ms Emmy's reflections.
