Brilliantly conceived, superbly directed, and beautifully acted, Babel is inarguably one of the best films of 2006. Director Alejandro Gonzlez Irritu and his co-writer, Guillermo Arriaga (the two also collaborated on Amores Perros and 21 Grams) weave together the disparate strands of their story into a finely hewn fabric by focusing on what appear to be several equally incongruent characters: an American () touring Morocco with his wife () become the focus of an international incident also involving a hardscrabble Moroccan farmer (Mustapha Rachidi) struggling to keep his two young sons in line and his family together. A San Diego nanny (Adriana Barraza), her employers absent, makes the disastrous decision to take their kids with her to a wedding in Mexico. And a deaf-mute Japanese teen (the extraordinary Rinko Kikuchi) deals with a relationship with her father (Koji Yakusho) and the world in general that's been upended by the death of her mother. It is perhaps not surprising, or particularly original, that a gun is the device that ties these people together. Yet Babel isn't merely about violence and its tragic consequences. It's about communication, and especially the lack of it--both intercultural, raising issues like terrorism and immigration, and intracultural, as basic as husbands talking to their wives and parents understanding their children. Irritu's command of his medium, sound and visual alike, is extraordinary; the camera work is by turns kinetic and restrained, the music always well matched to the scenes, the editing deft but not confusing, and the film (which clocks in at a lengthy 143 minutes) is filled with indelible moments. Many of those moments are also pretty stark and grim, and no will claim that all of this leads to a "happy" ending, but there is a sense of reconciliation, perhaps even resolution. "If You Want to be Understood... Listen," goes the tagline. And if you want a movie that will leave you thinking, Babel is it. --Sam Graham
