According to Mr. Skin, Natalie Portman’s naked ass will make
its debut in the new short film by Wes Anderson, Hotel Chevalier.

"In the Wes Anderson short, Hotel Chevalier, eight minutes
in we have Jason Schwartzman beginning to undress Portman. After taking off her
boots, he sits on the bed while she stands in front of him. He pulls
down her pants revealing her panties. He then pulls them off and, voila,
there's Portman's ass. Full view. No cutaways. No Goya body double.It's
a one shot and it's all her. At 10 minutes in there's another
shot of Portman standing naked leaning on a dresser. We see just a
little bit more ass but her clearly naked body covers strategically covers up
the rest."

So,
her she is in scenes from Closer, topless in a thong showing of the beauty of
her rear end.
