Doppelgangers in Paint

Hercule Poirot?

No, it's a portrait of the painter Toulouse Lautrec by Giovanni Boldini. Source

And now for something a little different.

I was looking at a certain painting the other day and remarking to myself how much the portrait's sitter reminded me of a certain fictional detective. (see above) Then, as these sorts of things usually do, I happened upon another painting which reminded me of yet another fictional detective. That's when the light bulb flashed over my head.

Why not see how many fictional detectives I can cast from portraits? Just for fun, I mean. The history of art is an enormous department of central casting. At some point it might be fun to cast a whole movie or a whole book from paintings.
