Australian director Baz Luhrmann has brushed aside reports that 20th CenturyFox was so concerned about unenthusiastic audience response during testscreenings of his blockbuster movie Australia that it forced him tochange the tragic ending to a more positive one. "You really think that onmy films people tell me what to do?" he said to a Reuters reporter. "I don'tthink so -- on my films I decide." Luhrmann said that he had written sixdifferent endings for the movie and had shot three of them. The one that hehad selected, he said, will be a "surprise."
