-There are no details but, according to the below article, Elisabeth Moss has nude scenes in the Sundance Channel miniseres Top of the Lake, which premiered at Sundance and airs on television beginning March 18.
As for Moss, this is the performance that could set a very promising tone for her post-Mad Men career. She’s stripped bare, both emotionally raw and literally. The actress initially balked at being naked, she told me after the screening, “You don’t want to be put in any position—pun intended—that’s not good.” But then she figured that “Jane Campion is the most feminist woman on earth; she’s going to be the last person to take advantage of you. She just made me feel safe. Most importantly, too, she was like, ‘You’re gonna look great!’”
-There are no further details, but this Hitfix review seems to confirm Riki Lindhome's nudity in "Hell Baby".
Riki Lindhome makes a striking entrance in the film, naked in ways I did not know you could be naked, but she has comic chops as sharp as anyone else in the film.
