On seeing the movie for the first time last night: "I think I cut off Dermot [Mulroney]'s circulation just squeezing his hand with excitement and thrill to see what everybody did. Because it's such a great ensemble. Even though there were a lot of scenes that we are all in together, my favorite is the bus station scene with Benedict [Cumberbatch] and Chris [Cooper]. It was my favorite scene in the play and it was my favorite scene when I read the screenplay. To watch the way they did that in the film, it was heartbreaking. I have too much makeup on right now to keep talking about that scene! But that's why you want to go and see what your friends did so perfectly. It's great. I loved watching the movie last night and I thought the audience was so great. It was great to have so much energetic support. It was something I'll never forget."

On working with Meryl Streep (part 2): "To work with Meryl Streep is a dream come true for anyone. To know her is an honor. She is such a beautiful person and it was intimidating, certainly, to be in these scenes with her. Choking her, and things like that, were not how I pictured it going in my mind all these years. I thought we'd be together, having tea and speaking in fabulous accents all dressed up. But there we were... I'm sweating and have on a big butt pad. So that's not how it was in my dream. However... It was still amazing. I think that at the end of every day -- coming out of the truth of the Weston family and into our own truths of who were are together with a hug and a kiss and an 'I love you' -- that was really the elixir that I needed to come in the next day and climb over the next table to choke her in the next way."

On what she does to alleviate anger: "Act! I don't have to be angry now for like 10 more years after this. I got it all out!"

On the fact that the actresses that played her sisters are named Juliette and Julianne (after a reporter tried to pose a question to all three of them): "Isn't that hard to say? Imagine what John [Wells] went through! Why did he cast the three of us? It was a Jule-bilee! [huge laughter from the audience] Just take a minute people. Enjoy that. Cause it's hard to say, too."

On working with Meryl Streep (part 3):  "Meryl is not only sublime and superior in her work. She's such a beautiful person. She sees not only what I need as an actor but what I need as a girl in the world. She provides all that, all the time. No wonder she's sleeping. She's exhausted after taking care of me."
