I was also so pleased with Bryce Dallas Howard as Hilly Holbrook. Hilly is a villain. In the book, as well as the movie, you just hate her. Bryce did an amazing job. In fact, when I first found out that she was cast I was so sad. I really wanted Anne Hathaway to be the villain so I could hate her without anyone asking why. However, after the movie I said to my mom, "It is a good thing that Anne Hathaway wasn't in it. I would have hated her no matter what she did with the role. Bryce is an actress I like, and she MADE me hate her."
And finally, my favorite person in the movie brought a character to life for me. Jessica Chastain was so amazing. I think she is my new favorite actress. She was so darling in the role as Celia Foote. She was tough but charming and delicate. I won't spoil it for those who haven't seen it, but she had a few parts that just sold me. I think she put 100% into expressing the character in every movement.
So here is to a great book and a great movie. Emma Stone was asked what she thought was the number one thing people should take from this movie. Without a breath she emphatically said, "Courage!" I completely agree.
