The Atlas Shrugged movie now not only has its own page in the Internet Movie Database (which has probably been the case for a while), but their IMDB page also offers this update, as of 30 Jan 2007, on the movie’s status:
Status: Announced
Comments: The screenplay is nearly complete, and production is scheduled to begin this year (2007).
Status Updated: 30 January 2007
Note: Since this project is categorized as being in production, the data is subject to change; some data could be removed completely.
Hope springs eternal. 
I also see that Randall Wallace, of Braveheart and Pearl Harbor fame, is now listed as the screenwriter — rather than the previously-cited James Hart.
