Jeanne: (On working with actresses Chloë Sevigny and Ginnifer Goodwin in Big Love) It's really been dreamy. We are vastly different people and it just comes together like a puzzle, just beautifully. The three of us acting was truly one of the best experiences I've ever had. I really look forward to the days when all three of us shoot together, because the sparks really fly.
