Der Unfisch (1997)

In this charming fairy tale, a magical whale wreaks havoc in a small Austrian village. It all begins with a traveling showman and his giant stuffed whale. Roberto and his cetaceous companion have been touring the country for years. Just before he arrives at the aforementioned mountain village, he suffers a fatal heart attack. The townsfolk wheel the great whale into the town square and leave it there until they can find one of Roberto's relatives to pick it up. Eventually, they locate the lovely Sophie Moore. As she arrives, Carl is jilted by the free-spirited Maria at the alter. He vows never to leave the spot where she left him. But then he sees Sophie and changes his mind. The two pry open the whale's mouth and step into its belly. A magical feeling overtakes them and they make love. The entire time, Carl dreams of his Maria. Miraculously, she is waiting for him at the whale's mouth and is ready for marriage. Sophie doesn't know what to make of this turn of events. Suspecting the whale is magic, she quickly takes another lover into its bowels. Unfortunately, he was once jilted by Maria and wishes her to become a dog. The deed is done. Horrified, Sophie begins sleeping with every man in town in the hope that one will wish Maria was a woman again. Unfortunately, the men have other, more selfish wishes on their minds. Things get worse when Sophie discovers that the magic will only work once for each man. ~ Sandra Brennan, Rovi
