"Two Days, One Night" might be the best Dardennes movie yet. Marion Cotillard is mesmerizing in her role as Sandra, a young Belgian mother who discovers her co-workers were pressured to choose between getting a significant pay bonus and having her keep her job. The way Cotillard approaches each and every co-worker, pleading — sometimes even begging — for them to change their vote is heartbreaking. It’s a movie that once again places the talented directing duo on the short list of the very best filmmakers in the world today. I met up with them a few months back to discuss the process, Cotillard and the small details that make a Jean-Pierre and Luc Dardenne film so damn great.
