Joachim Trier's follow-up to his acclaimed debut Reprise (which won the Discovery Prize at the Festival in 2006) is a brilliant update of the Pierre Drieu la Rochelle novel Le Feu follet, previously adapted into the classic film of the same name by Louis Malle (which screens in this season's Summer in France series). Returning to Oslo after graduating from an addiction recovery programme, Anders (Anders Danielsen Lie, the star of Reprise) finds himself rejected by his former friends, and following a horribly, comically botched job interview, drifts aimlessly around a city that is increasingly foreign to him. Substituting post-millenial angst for the nameless existential dread that drove the novel and Malle's adaptation, Oslo, August 31st is a gorgeously realized elegy to misspent youth, the darkness of its long, deadly hangover still intermittently illuminated by fleeting beauties.
