Is Sienna Miller in Vogue?

If you were one of the handful of people who caught Sienna Miller as doomed Warhol superstar Edie Sedgwick in Factory Girl, you might recall that one of the supporting characters was legendary Vogue magazine editrix Diana Vreeland, played in the film by Illeana Douglas.

The real-life Vreeland was a larger-than-life fashion maven who shaped and influenced the styles of generations of American women.

Now comes word that Vreeland herself will be the subject of a new movie, and Miller is at the top of the wish list to play her.

One of the producers behind Unzipped, the hilariously revealing documentary about gay fashionista Isaac Mizrahi, hopes to bring Vreeland's memoir, D.V., to the screen.

No word yet on when the film might go into production, but cross your fingers that it's as glamorous as its subject matter.
