Her long fringe, her British accent, and her relationship with Serge Gainsbourg in the 1970s have left their mark on the imagination. As an actress and mother, muse and activist, singer and sex symbol, Jane Birkin’s panache has spanned the decades of the past 50 years, raising her to the rank of icon. A child of the baby boom, Birkin took after her mother, the English actress Judy Campbell, in her passion for performance. In her 20s she played a series of minor roles in the Swinging London of the 1960s, but it was later, in Paris, newly divorced from an unfaithful John Barry, that she became successful. In 1968 young Birkin sealed her fate when she met Serge Gainsbourg on the set of Slogan. Together, they were the embodiment of a mythical couple. She inspired his greatest songs, and he showed her that her boyish figure, for which she had been teased in her youth, could be a model of femininity. But when Gainsbourg gave way to Gainsbarre, his destructive alter-ego, Birkin emancipated both herself and her baby-doll persona. In the 1980s she moved from popular to auteur cinema. Directed by Varda, Tavernier and Doillon, she exudes melancholy sensitivity. On the stage, in song, on either side of the camera, or in the streets, ‘Jane’ has joined many battles (for civil rights, ecology, the fight against Aids…) as a tireless explorer of freedom. Made entirely from archive material, this documentary shows how Birkin, at first inseparable from Gainsbourg, never stopped reinventing herself and multiplying her roles. Moving from scenes of daily life to recording sessions, from film excerpts to interviews – where the actress and singer reveals her mischievousness – director Clelia Cohen sheds light on the many faces of the timeless Jane B: fragile child, Lolita to a Pygmalion, bohemian mother, accomplished actress, competent singer or militant activist. An exhilarating portrait of the woman who seized, with her gap-toothed smile, the status of an icon with candour and audacity, shyness and shamelessness.
