 One of the characters in this film is called the Grand Duke Vladymir  of Russia (played by Alfredo Mayo as required by the script: a  drunken aristocrat who is after Maria Lujan (Sara Montiel). It so  happened that there was in real life a Russian Grand Duke by that  name and he sued the film for portraying him in such an unflattering  manner. The problem was resolved when Cifesa (the films  distributor) agreed to pay the indignant Duke an undisclosed large  sum of money and removed from the soundtrack any reference to  Vladymir of Russia. Since then all you hear in the movie is  references to "Grand Duke" but no name.
