I have fallen in love with this musical through clips on YouTube. You guys probably know all about it but I am so excited that it's come to Broadway next year. It looks simply wonderful!
Here's a video of the four Matilda's who shared the part. I hope it's okay to post this here.
I thought Milly opened on Broadway and was the youngest
No, it was Sophia.
Sophia is 9, while the rest of the girls are 10. She's also the smallest Matilda.
Hehe! They did well on our accent! :D
