Since you all keep talking about it I'll confess I immediately did a double take on first viewing of that scene since the walk of shame body didn't really look like Lena's real bod (hey, those do not look like her real bewbs) since she's done nude scenes before.
The hubbub about it was a little out of scale. With that said, the nudity in that scene did enhance the humiliation factor, similar to a scene in the WWII movie
Black Book with Carice van Houten (who plays Melisandre in GoT).
Speaking of body doubles, Catherine Bell (a then totes unknown actress) was Isabella Rossellini’s nude body double in
Death Becomes Her.
A interesting start for someone who became a TV star in her own right after that.
