On Top of the Whale (Dutch: Het dak van de walvis) is a 1982 Dutch surreal and magic-realistic fantasy film directed by Chilean Raúl Ruiz while he was in exile and "...is one of his most delirious and ambitious hoax-like fictions". The film employs the use of six different languages, including an invented one. The story follows a Dutch anthropologist and his wife and child who are invited to the house of a communist millionaire in Patagonia (an area located in Chile and Argentina) to study the last two surviving Yachanes Indians.
