...or am I losing my mind?

Full disclosure: I liked the movie but not enough to see it again only for the purpose of choosing my favorite image so I just saw the first 10 minutes of it. I don't even recall the plot, but I think I remember what's important and that is that Joan is losing it in this movie.

I like this image because it seems as if the doctor is examining how well Joan is taking care of her nails.
Miss Crawford was an intimidating beauty and a true diva, less known for her acting skills (in comparison to Katherine Hepburn, Bette Davis etc) and more for her looks and charisma. You would expect her to care about looking gorgeous in every single movie she appeared in, but in the case of Possessed she seems more eager to showcase her craft than anything else.

So, it's funny, to me, that this image, in a way, alludes to Crawford's polished appearance, when the movie cares about anything but that.
