Laura Linney had to deal with a different kind of physicality in the film, appearing completely nude in a lengthy scene in which her character Callie poses for Lyle in his art studio-not exactly a love scene, but with subtle sensual overtones. "It's always difficult, at least for me," she said. "It's just not a natural thing to do! I'm very glad that it was Rob behind the camera," she said, acknowledging that actors-turned-directors are "always helpful-if they're good. They're going to understand acting in a much freer way."
