Spielberg's movie "Lincoln" appears to be in pre-production, with full production planned for autumn; this suggests a late 2010 release date. This project crept back into the news this month with NY Senator Schumer's public request that it shoot scenes at Seward's home in Auburn.
A student newspaper says the film will be based on Goodwin's Team of Rivals, but this information is probably based on stale newspaper clippings. All stories reporting on Tony Kushner's involvement simply say he is writing the script without mentioning adaptation.
In February, it looked as though a December 2009 release was planned, then that the film was dead, then Spielberg missed a President's Day announcement deadline, then news emerged that Disney would probably make it. So this is progress.
BTW, what proportion of projects make it out of pre-production?
