My Geisha
Paul Robaix is a well known director, married to Lucy Dell (Shirley MacLaine), a famous movie star who has starred in many of his movies. But his next project is Madame Butterfly and he wants a Japanese actress for the role although Lucy is desperate for the part.
Despite her protests Paul casts the geisha Yoko Mori as Madame Butterfly. It is only part way through filming that Paul realises that the exotic leading lady, for whom he has fallen, is in fact Lucy.
