Le battement d'ailes du papillon

The fluttering of butterfly wings in the Atlantic can unleash a hurricane in the Pacific. According to this theory (somehow related to the Chaos Theory, I'm not sure exactly how), every action, no matter how small or insignificant, will start a chain reaction that can lead to big events. This small jewel of a film shows us a series of seemingly-unrelated characters, most of them in Paris, whose actions will affect each others' lives. (The six-degrees-of-separation theory can be applied as well.) Each story is a facet of the jewel that is this film. The acting is finely-tuned and nuanced (Audrey Tautou is luminous), the stories mesh plausibly, the humor is just right, and the viewer leaves the theatre nodding in agreement.
