Third movie with Kirsten Dunst ?
From the Town and Country's Kirsten Dunst interview (September 2015) :
In addition to Fargo, which returns in the fall, Dunst has Midnight Special coming out in November, a sci-fi chase movie from Jeff Nichols (...) There's also talk of a third film with Sofia Coppola in 2016. It's telling, I say, that she's a muse to strong women like Coppola and the Mulleavy sisters. "The feeling is mutual," she says. "I consider them muses, too. We feed off each other."

Any idea of what it could be ?
