In the middle of the night, a 7-year-old boy has gone missing. The crisis has drawn the child’s father Julien (Guillaume Canet) back to a small, snowy town in eastern France in an effort to help. Julien travels abroad for work and has been essentially absent from his son’s life since splitting with his wife (Mélanie Laurent) a few years earlier. MY SON marks the third and most unique collaboration between Canet and director Christian Carion, whose 2005 war drama Joyeux Noël earned an Academy Award nomination for Best Foreign Language Film. Here, in a remarkable filmmaking twist, Carion made the decision to keep Canet almost completely in the dark about the movie’s plot. The film was shot in sequence over a quick six days. And Canet, onscreen for virtually every minute, was experiencing events, struggling with his emotions, and discovering clues in real time, just as his character was. The result is a dynamic thriller with an added layer of authentic tension.
