Uma and Katherine's "Motherhood"

"It's rare to find material like this," Uma Thurman (right) said of director Katherine Dieckmann (left) and her script for "Motherhood," premiering tonight at the Sundance Film Festival. "One thing I've been pretty good at is feeling good writing. I have a good eye for that and my favorite thing is to find writing about our experience now as people. Contemporary material that is looking at our lives today. That's my favorite, if you can call it, genre. And finding contemporary, humorous but dramatic writing that is fresh and open-eyed in the moment is very difficult."
