It’s not just David Fincher‘s Zodiac (Paramount, 9.22) that’s probably going to run about three hours, but also Andrew Dominik‘s The Assassination of Jesse James by the Coward Robert Ford (Warner Bros., October), which stars Brad Pitt, Casey Affleck, Sam Shepard and Sam Rockwell. I don’t know anything rock-solid, but it seems fair to deduce that the James film will run long because Dominik’s script is a whopping 210 pages, whereas James Vanderbilt‘s Zodiac script runs about 190 pages…do the math. Here, by the way, is a well-written appraisal of a 2004 draft of the James script, posted six days ago by novelist and historian Frederick J. Chiaventone, a Missouri resident who’s been interviewed for an “American Experience” documentary about James.
