Call it a classic, coming-of-age moment: Gwyneth Palthrow's character in Sliding Doors goes from long, dull, mousy brown hair to a cool-girl pixie cut that was huge in the late '90s, with perfect chunky highlights. One staffer said: "I loved that they still manage to style it loads of different ways even when it was really short. Not gonna lie, I did the little twists with the flowers, even though my hair was 8 inches longer than hers."
