Mother and Child has some surprising nudity for a film rated PG here.
At 11 minutes, Kerry Washington is having sex with her husband and we see her breasts.
Half an hour into the film, Naomi Watts shows her ass as she gets out of bed nude and puts on a robe. Naomi walks out to the balcony and sees her neighbor drinking coffee. Naomi then opens her robe and flashes him her left breast and bush just like in the paparazzi pics that have been going around. At 47 minutes, Naomi is lying face down on the bed with her skirt hiked up so we can see the bottom of her ass.
