• Marion Cotillard on Nicole Kidman in ‘Rabbit Hole’, Variety, November 29, 2010

felt what she felt. I cried with her. I understood every fragment of her inner disaster and the way she survived. Nicole is at the same time a rough and a cut diamond. She has a very simple and direct way to enter your heart. She shares her emotion in the most generous way. She is simply one of the world’s best actresses.

And one where Kevin Spacey talks about Leonoardo DiCaprio and Marion Cotillard:

Leonardo DiCaprio. I thought his work in ‘Inception’ was really great. His work in ‘Shutter Island’ was also great. And anytime he’s onscreen with Marion Cotillard is extraordinary. She, also, is incredible. Their relationship is so much the heart of that film — everything he was trying to shift and change so that the ending would be different. It’s remarkable. And it’s such a complex story. If you left that movie to go get popcorn or take a pee, you were screwed.
