a missed train . a wrong phone number . an extra cup of coffee . what happen to those around you when you make a seemingly innocuous decision . most people do not give it a think a they absorb in their own thought and action . happenstance tell the story of the interrelation and cause and effect of the mundane a it pertain to a group of normal parisian folk . it have all the component of what pass for contemporary theater and with the full cast of the dysfunctional and disillusion . there a cheating husband and an illegal immigrant and a classic slacker and a pickpocket and a crazy grandmother and an annoying girlfriend and a selfish roommate and and a homeless man . audrey tautou serf a the erstwhile protagonist ( in the sense that she on camera as much a anyone else and open and close the film ) and normal girl who just can not seem to find the right rhythm in her life . she learn at the beginning of her day from a stranger on a train what her horoscope hold for her . what happen to her in the course of the day be tell through various character . do the prediction come true . the concept be good and but the storytelling be flimsy . the connection from one event to the next be weak . there well storytelling in 15 second of the liberty mutual insurance commercial where one person see a good deed and pass it along to another than there be in two hour of happenstance . if you enjoy audrey tautou and then you certainly can sacrifice the time for this film and but you will finish it dissatisfied and wonder what this same storyline could be if it be handle by a good producer and director .
