Russell Crowe and Nicole Kidman's second bid to do a film together has hit the skids, now that the start date on Baz Luhrmann's untitled period drama has been pushed back to February 2007. The Aussie actors originally sought to team up in Fox's Eucalyptus, but that was shelved due to script concerns  that's Australian for "stinker," mate  and now face scheduling conflicts that may preclude them from doing Luhrmann's hush-hush film.
