I liked this film better than most people did, but I don’t think it’s “political”, unless you mean that in the sense of “Everything those in power do is political, including their clothing choices and sexual peccadillos.” (I’m remembering Imelda Marcos’ vast shoe collection, and JFK’s Heartbreak of Satyrisis — and what it says about both of them as leaders and human beings.)
I took Marie Antoinette as the look at a woman who, because of her family, had to live her life in public, and what that does to a person. Sofia’s “schoolyard grapevine” was the global entertainment press, reporting on her father wagering the family estates again, who he’s sleeping with/getting high with while Mom’s at home raising kids and cutting footage, and so on. She obviously felt a lot of empathy with Marie Antoinette….
Contrast this to Stephen Spielberg and Kate Capshaw, who despite their fame and careers live their married life as privately and Middle-Class “normally” as possible. Admittedly it’s made easier by Capshaw (unlike Spielberg’s first wife, Amy Irving!) largely choosing to be a stay-at-home Mom, and only taking on a movie when it really interests her. But in the end, both halves of this “power couple” want that for themselves, and for their children — I wonder if Sofia Coppola wishes her folks had wanted that for her, too?
