Shadows on Vienna
In one of the publicity photos, see e.g. http://www.virtual-history.com/movie/photo/m01/large/joan_crawford.jpg, a strange shadow is cast over Joan Crawford. Although all scenes involving any closeups of Crawford were done in studio, not sure if this one would be included, but in wide shots of the cabin there is absolutely nothing that might cast any such shadow.
Does anyone have any thoughts about what it might be a shadow of?
