Kate Winslet is Lee Miller

When Kate Winslet set out to try and make a film about the photographer Lee Miller, she knew it couldn't show everything. 

"She lived such a vast life, it would have been impossible to make a film about all of it," Winslet told TIME when speaking for a recent profile. 

So Winslet, who produced the film and stars in it, decided to home in on one era in particular for what would become Lee, which premiered at last year’s Toronto International Film Festival and is out in theaters Sept. 27. The movie, directed by Ellen Kuras, mainly takes place during World War II when Miller was on the front lines, taking some of the most iconic photos to emerge from the Blitz, the liberation of Paris, and the Dachau and Buchenwald concentration camps. Winslet portrays Miller as an unapologetic force and pioneer in her field, who is specifically attuned to the suffering of those she captures in images.
