Leo Tolstoy used Maupassant as the subject for one of his essays on art: The Works of Guy de Maupassant.
Friedrich Nietzsche's autobiography mentions him in the following text:
"I cannot at all conceive in which century of history one could haul together such inquisitive and at the same time delicate psychologists as one can in contemporary Paris: I can name as a sample – for their number is by no means small, ... or to pick out one of the stronger race, a genuine Latin to whom I am particularly attached, Guy de Maupassant."
Gene Roddenberry, in an early draft for the The Questor Tapes, wrote a scene in which the android Questor employs Maupassant's theory that, "the human female will open her mind to a man to whom she has opened other channels of communications." In the script Questor copulates with a woman to obtain information that she is reluctant to impart. Due to complaints from NBC executives, this part of the script was never filmed.
Michel Drach directed and co-wrote a 1982 French biographical film: Guy de Maupassant. Claude Brasseur stars as the titular character.
