Who's that mysterious Oriental beauty? It's Shirley MacLaine! Meet Lucy Dell (Shirley MacLaine), an enormously popular Hollywood comedienne married to movie-maker Paul Robaix. And meet Yoki Mori (also MacLaine), the recently discovered geisha star of Paul's in-progress film version of Madame Butterfly. Paul doesn't know it yet, but that's no geisha - that's his wife! Yves Montand (as Paul), Edward G. Robinson and Bob Cummings join MacLaine in the romantic comedy My Geisha. Paul is eager to prove he can make a hit film without his wife. Lucy, however, wants to prove she can handle a dramatic role. So she secretly follows Paul to Japan, dons a disguise and gives a topsy-turvy spin to this delightful, gorgeously filmed comedy of mistaken identities.
