 Theres a little dig in the scene when Cecil B. DeMille (qv) finds  out that Paramount has been calling Norma Desmond because it wants  to borrow her car for some Bing Crosby (qv) picture. The truth of  the matter was that Crosby was one of the very few actors to whom  Billy Wilder (qv) had objected, mainly because he had done the  unthinkable during filming of _Emperor Waltz, The (1948)_ (qv) and  rewritten some of Wilders dialog.
