Please help me find the title of a movie where a man makes a bargain with the devil, refusing to bathe or cut his hair and nails for 7 years in exchange for great wealth. During his hairy phase he meets a woman who sees beyond his appearance and he makes her a ring out of one of his fingernails. When the 7 years are over she no longer recognizes him.
