DER TOTE ONKEL (1982)

Joseph von Träubesser is a scion of a wealthy aristocratic family. He's not satisfied with idle bliss but is ambitious and tries to become a good painter. His family and especially his nephew Leonid, who could be taken for his twin, think he's cracked. Fabian Cabanas, a famous painter, isn't at all pleased with his life. Apion Herbst, a postman and spiritualist, holds séances when off duty and helps Fabian to a new body. And Joseph too profits from this séance.
