On the first day of filming, Meryl Streep told Anne Hathaway, "I think you're perfect for the role. I'm so happy we're going to be working together." Then she paused and followed it up with, "That's the last nice thing I'll say to you." And it was. Many fashion designers allowed their clothes and accessories to be used in the film, making it the most expensively-costumed film in history. Meryl Streep donated her wardrobe to a charity auction.
