Barbara the Fair with the Silken Hair (1970)

Once upon a time there lived a tsar by the name of Yeremey (Mikhail Pugovkin). He went on a year-long travel over his realm to take inventory of everything that belonged to him. One day he bent over a well to have a drink of water and was immediately grabbed by the underwater tsar Chudo-Yudo (Georgiy Millyar). The latter demanded a ransom for Yeremey s freedom something that he had no knowledge of in his tsardom. And indeed, Yeremey had no idea that in his absence the Tsarina had given birth to a son.
