I was trying to suggest that the person who adopted the professional name of Boris Karloff was quite different from the monster that he portrayed in movies. In a similar way, maybe the mathematician John Nash was quite different from the picture you said reminded you of Karloff.

I think one can get from his picture, if one is a sensitive observer, along with whatever other information you might have about him, quite a lot of information, or suggestive insights. His face struck me as showing uncertainty, weariness, and some distress. Not something you could claim as certainties, but as suggestions as to what he had experienced. Not surprising if you knew his life history.

I think one can read quite a bit from people's faces (and actions) in general. It can be quite entertaining and useful.
