For this sobering effort, Syrian-born filmmaker Talal Derki ("Return to Homs") held himself out as a jihadist sympathizer--and received an unprecedented two years’ access to the home life of al-Nusra co-founder Abu Osama. With primary focus on the upbringing of Osama’s two eldest sons, a portrait of an otherwise mundane adolescence informed by violent absolutist doctrine emerges that is both provocative and stunning. 99 min. Widescreen; Soundtrack: Arabic; Subtitles: English. In Arabic with English subtitles.
