Like Philippe Falardeau's recent hit Monsieur Lazhar, his earlier, tragic-comic 2008 film features exceptional, guileless and pretenseless performances by young and/or amateur performers. Here, it's Antoine L'Ecuyer, who plays Leon Dore, a 10-year-old whose destructive acts and pathological lying may remind some of the bad behaviors by comic strip character Dennis the Menace. However, Leon's actions have serious repercussions for him and others.
