Writer/director Laurent Firode‘s 2000 film Happenstance (Le Battement d’ailes du papillon) is a fabulous French-language romantic comedy starring Audrey Tautou, one of my favorite actresses, as Irene, the leading character. It is a romantic comedy that uses its simplicity to showcase the elements of Chaos Theory or the Butterfly Effect, where one action leads to a series of progressively larger actions so that, for example a butterfly in Indonesia can cause a hurricane in Florida.
