The Stringer, which premiered at Sundance, alleges that an incorrect credit was given for iconic ‘Napalm Girl’ picture

A controversial new documentary that premiered at the Sundance film festival on Saturday night disputes the authorship of one of the most famous press photographs ever taken, challenging 50-plus years of accepted history.

In The Stringer, directed by Bao Nguyen, a group of journalists and investigators claim that the photograph colloquially known as Napalm Girl – an indelible image of American war in Vietnam that galvanized the anti-war movement in the US – was not taken by Nick Ut, the Associated Press staff photographer long ascribed credit by the news group.

Sundance film festival: A primary school teacher in Russia pushes back on cruel nationalist propaganda in a fascinating and daring look at everyday encroachment

Pavel Talankin is, by his own admission early in the extraordinary documentary Mr Nobody Against Putin, not the person you or he would pick to be the hero of the story or to take on an oppressive regime. To stand up to Vladimir Putin takes a considerable amount of courage and a not inconsiderable amount of resources; Pasha, as he is known to his students, is a teacher at a small primary school in Karabash, a mining town in the Ural mountains remarkable only for its renowned levels of toxic waste, and would have been more or less content to remain the titular nobody far from Moscow. He loves his hometown, its smokestacks and Soviet buildings, but most of all loves the curiosity and enthusiasm of his students, all filmed by Talankin in his capacity as school videographer.

But Talankin has always cut a bit of a non-conformist streak – he is the one teacher with a Russian democracy flag in his classroom, a safe haven for the school’s punks and artsy weirdos, or anyone with a desire to speak freely. He is openly alarmed, to the extent one can be, when the school begins enacting Vladimir Putin’s new “patriotic education policy” following Russia’s invasion of Ukraine. He keeps doing his job, filming the new blatantly nationalist curriculum, the lies about the necessity of invasion told as fact, the forced military drills and oaths of loyalty forced on initially bored and apathetic children.

A new documentary celebrating the life and legacy of the late singer-songwriter Jeff Buckley premiered to an emotional crowd – including his mother and former bandmates – at the Sundance film festival.

Met with a standing ovation and plenty of tears, It’s Never Over, Jeff Buckley delves into the troubadour’s influences, career and personal relationships cut short by his accidental drowning in Memphis’s Wolf River in May 1997, at the age of 30. Directed by Amy Berg, the 106-minute documentary includes numerous snapshots from Buckley’s many notebooks as well as a trove of childhood photos, archival recordings and interviews with those closest to him, who remember a sensitive and voraciously curious musical talent.
