April 4, 2014 -- Kristen Bell said she always dreamed of voicing a Disney princess.
With "Frozen," in which she voices Princess Anna, her dream came true.
"Disney animation was so important to me, but what's even more special is that I was able to help shape a type of heroine that I wanted to see that I would identify with when I was 5 to 10 years old," she said. "I feel like I'm so, so proud of Anna because of all those things and her ability to believe in people even when they stop believing in themselves is very apparent."
The movie tracks Anna's progress from childhood to adulthood, and that presented Bell, 33, with the unique challenge of singing as a girl, a teenager and a grown-up.
