Love for an Idiot 1967 (Japan), also known as Chijin no ai is Japan drama premiere on Apr 27, 1967
This was the third film version of Junichiro Tanizaki's novel that might be described as an eccentric Pygmalion. A middle-aged businessman takes in an orphan girl with intentions of raising her to be a proper lady who might eventually become his wife. But it is the girl who gains control. She takes advantage of her sugar-daddy's doting to get whatever she wants, coquettishly playing on his less than honorable intentions. After years of being cuckolded, the poor fool is still her slave.
