“Teenagers do horrible things to each other in the name of their ”ideals.” But adults do too, which is so much worse. That’s the sad truth behind Ginger & Rosa, a touching drama from British art-house filmmaker Sally Potter, who broke through to wider audiences with 1992’s Orlando and has now made her most mainstream movie yet. Set in 1962 London during the Cuban Missile Crisis, the story follows the tenderhearted Ginger (Elle Fanning), who lives with her thwarted-artist mother (Christina Hendricks) and her lefty academic father, Roland (Alessandro Nivola). She spends her days at pacifist marches with her wild best friend, Rosa (Alice Englert), and an older American activist (Annette Bening). Soon the BBC is reporting that the bomb may be dropped any day, and it feels like the end of the world to both girls. But then, when you’re in high school, it always does. And you get the sense that even if the Cold War had never happened, Ginger and Rosa would find another cause to get worked up about. Still, Potter has enough compassion for these girls to imply that their lives might really be just as dramatic as they think. In dreamy, color-drenched scenes that look like they’re turning into memories right before your eyes, Potter portrays their friendship as a great love-in-wartime romance”—Entertainment Weekly. “Ardent and intelligent…The period details seem just right!”—A.O.
