Sally Potter, director of the outlandish “Orlando” (1992) and “The Tango Lesson” (1997), continues her skein of interesting and quirky productions with “Ginger & Rosa,” a coming-of-age story set in London in 1962. The story: Two teenage girls — Ginger & Rosa — are inseparable. They skip school together, talk about love, religion and politics and dream of lives bigger than their mothers’ domesticity. As the Cold War meets the sexual revolution and the threat of nuclear holocaust escalates, the girls face the clash of desire and the determination to grow up. Ginger (Elle Fanning) is drawn to poetry and protest, while Rosa (Alice Englert) shows Ginger how to smoke cigarettes, kiss boys and pray. Both rebel against their mothers: Rosa’s single mum, Anoushka and Ginger’s frustrated painter mother, Natalie. Meanwhile, Ginger’s pacifist father, Roland, seems a romantic, bohemian figure to the girls. He encourages Ginger’s Ban-the-Bomb activism, while Rosa starts to take a very different interest in him. As Ginger’s parents fight and fall apart, Ginger finds emotional sanctuary with a gay couple, both named Mark, and their American friend, the poet Bella. Finally, as the Cuban Missile Crisis escalates — and it seems the world itself may come to an end — the lifelong friendship of the two girls is shattered. “Ginger & Rosa” takes the familiar teen-coming-of-age genre and subverts it into a sensitive look at the real joys and sorrows of growing up, presenting her characters with more predicaments than most kids have to face and merging the personal with the political. Potter ups the ante of coming-of-age tales set in the 60s — or any decade, for that matter — by adding in the anti-war sentiments and a love affair between one of the girls and the other’s dad. And, the icing on the cake: Elle Fanning is spectacular as Ginger. Extras include deleted scenes, cast interviews, an audio commentary with writer-director Potter and two featurettes going behind-the-scenes into the making of the film.
