Steve McQueen can sustain a static frame like no other director. But such scenes also depend heavily on the consistency and focus of his actors. Like Liam Cunningham and Michael Fassbender’s astonishing conversation in Hunger, Carey Mulligan brings on her A-Game here. With melancholy eyes and a rich, searing voice, she sings a pitch-perfect rendition of this classic tune, and makes it impossible for us to take our gaze away from the screen. What makes the scene so powerful is the way Fassbender and Mulligan communicate their mutual emotions without words. Though never seen together in the frame as she sings, their chemistry is as intense as any shot they share. Their eyes really speak a thousand words.
