Tomboy (2011)

In "Tomboy," 10-year old Laure(Zoe Heran) moves to a new neighborhood with her parents(Sophie Cattani & Mathieu Demy) and younger sister Jeanne(Malonn Levana). While looking out from an apartment window one pleasant afternoon, Laure sees a group of boys playing out in the park. When she finally leaves her sister and sleeping, very, very pregnant mother behind in the apartment, the boys are gone, with only Lisa(Jeanne Disson), a girl of her age, left behind in their wake. Laure introduces herself as Mikael and they run after them together, so they can join in the fun. With that simple, elegant setup, writer-director Celine Sciamma tells an evocative and naturalistic genderblender with a very belieable sibling relationship. Sadly, the movie eventually runs straight into a narrative wall. Until then, Laure is not just being a tomboy; she is passing as a boy but not 24/7, so we'll keep to the feminine pronouns.(Actually, it is not until later that she is revealed not to be a boy.) She does this to enjoy the freedoms that boys enjoy but is too young to realize the minefield of gender that she has just walked into. That's where parents come in, as the movie smartly shows how parents help to shape their children's gender.
