Denis Villeneuve’s impassioned, decorous adaptation of Wajdi Mouawad’s award-winning stage play sees a dead woman bequeath her children a mystery, which in turn unlocks the secrets of her past and ultimately theirs. The Oscar-nominated Incendies is an arresting and satisfying fusion of political thriller and family drama. Handsomely shot and mesmerising throughout, it’s a film told most memorably in the sensitive and resonant performances of its lead actresses.
