A scout at Mr. Skin, has seen the film "Black Rock" and reports that both Lake Bell and Katie Aselton ("The League" and the director of the film) have nude scenes.

Lake, Kate Bosworth, and The League's Katie Aselton (who also directed) co-star as old friends forced to run for their lives on a hiking trip. Bosworth keeps her boulders in her bra, but Lake and Katie both bare boobs as they strip out of their wet clothes 52 minutes in, marking Lake's second career nude scene and Katie's nude debut.

Here are more details of Helen Hunt's nudity in "The Surrogate"

We counted four skinstances of Helen's cunt (a first for the As Good As It Gets star) in the nudity report, along with an impressive nine breast-baring scenes.

More info about the nudity in these films can be found at the below link.

One final note. Over the weekend I posted that Melanie Lynskey had a nude scene in the film "Hello I Must Be Going". A reviewer at Mr. Skin saw it and the only nudity from Melanie is a butt shot.
