Amy Adams

Why: This is the role that pays off the promise of Adams’ Oscar-nominated turn in "Junebug," demonstrating beyond a doubt her incandescent screen presence and breakout potential.

As an animated princess who tumbles into the real world, Adams plays her fish-out-of-water role with wide-eyed naivete and a pinch of magic, lighting up the lives of all around her.

Oscar or not, "Enchanted" will make Adams a star.
