In the pub across from the villa there hangs a poster on the wall which features a design promoting Alexander. Alexander was a magician who performed in the early 20th century and enjoyed great success in his presentations within the field of mentalism (e.g. mind reading, telepathy and the like). Alexander was often promoted as "The Man Who Knows", due to his ability to answer questions put to him by the audience under seemingly impossible circumstances. This, of course, parallels the function of the automaton which is featured in the film.
The cars on the street have Vienna, Austria numbers, W from Wien that is German name for Vienna city.
