From Inquirer:

Of Amanda Seyfried, who plays her bride-to-be daughter Sophie, the mother of three girls enthused, “From the moment Amanda opened her mouth in the first reading, I felt like she was one of my daughters. She shares many traits with my daughters. She is strong. She has a quiet voice but she has a stubborn streak. The word that keeps coming up about her is delicious. That’s the way I feel about my girls. It’s very easy to feel that Amanda was too young to get married, just like the way I feel about my girls.”
