The original title is "Jeux d'enfants" ("Love Me If You Dare"), is a movie from 2003 with Marion Cotillard and Guillaume Canet, and I really can't stop myself thinking about it. I laughed and I cried, it made me think about what is important in life, about parents and their mistakes, about forgiveness and true love. Not an American kind of movie, anyway.
I would put it on a list with the most powerful movies I ever saw, and I really recommend it, is genuine and beautiful.
