I read an essay in one of John Sutherland's books of puzzles in Victorian Literature about Mr Hyde's appearance. In films he is depicted as looking like a werewolf, but in the book he is described as being a small, young man, dressed as a gentleman. When asked to describe him further, witnesses say he somehow gives an impression of deformity, and without being able to say how, that his looks are unsettling. This made me think of the Uncanny Valley, which is an effect of computer or robotic human simulation. The simulations look close to lifelike, but somehow wrong. The best examples are the computer simulations of Carrie Fisher and Peter Cushing in Rogue One. If they ever re-film the book, they should represent Mr Hyde that way.
