As a screenwriter, Anders Thomas Jensen has produced some of the better Danish dramas of the new millennium (Open Hearts, Brothers, After the Wedding, In a Better World), but left to his own devices as writer-director he’s prone to somber black comedy (The Green Butchers). This one is all about genetic mutations: two grown brothers (Mads Mikkelsen, David Dencik) discover they’re adopted, reunite with their three biological brethren out in the country, and learn that all five of them are the products of their late father’s radical experiments. And hey, where did all these furry chicken come from? Occasionally rib tickling but more often gut churning, this turns largely on the spectacle of Mikkelsen, a respected dramatic actor and a Bond villain no less, being cast as a furiously dyspeptic nerd who keeps running off somewhere to masturbate. With Nikolaj Lie Kaas and Søren Malling. In Danish with subtitles.
