That's according to the Hollywood Reporter, which reports that the sisters have been developing the script for a few years now. The flick is called "Woodshock" and will star Kirsten Dunst, a friend of the fashion house who wore the hell out of a Rodarte gown printed with the Death Star at the Met Gala last year.
A Rodarte rep didn't immediately respond to a request for comment.
Of course, the Mulleavy sisters aren't the only fashion designers to dip into the film scene lately. In March, word got out that Tom Ford is working on his second movie, a noir thriller co-produced by George Clooney. Plot aside, we're interested to see how the Mulleavys's enchanting aesthetic, which has made for some beautiful runway show sets, translates to the big screen. If it's half as good as the world Ford created in his directorial debut, "A Single Man," they'll have done a bang-up job.
