While talking to ComingSoon.net this week from the set of Jonah Hex in New Orleans, Josh Brolin revealed that he is working on producing and probably starring in a movie about 19th century American abolitionist John Brown, who led the raid on Harper's Ferry in Virginia, attempting to free slaves in a 1859 event which many historians cite as a precursor to the Civil War. Despite John Brown's historical importance, he has been remarkably rarely depicted in film (though he was in the little-seen Seven Angry Men, 1955), and Josh Brolin notes in the linked interview that he thinks the time is finally right for a movie about this revolutionary abolitionist to get his own movie. Josh Brolin also mentioned talks he's had with Mel Gibson about a movie called Under and Alone, about the true story of an ATF agent who went undercover in a motorcycle gang.
