In the upcoming movie "Funny Games" starring Tim Roth and Naomi Watts, the plot is a couple of kids take a family hostage. At one point they ask Watts to strip, and she gets naked, although the movie does not state there is nudity, so I doubt we get to see it all. The clips do show her in her underwear a lot though.
