"Heat Vision reports director Scott Derrickson, behind The Exorcism of Emily Rose and the remake of The Day the Earth Stood Still, is set to helm Goliath, a period action movie based on the familiar tale of David vs. Goliath. While the movie is supposed to be set in historical times, it will have a contemporary feel not unlike 300 with a spirit that apparently embodies Bourne Identity."
"Anyway, our story begins with the warrior Goliath is sent to track down the foretold king of the Israelites as the young shepherd David suddenly finds himself in the middle of an epic chase and adventure that leaves him fighting not just for his own life, but for the very existence of his family and people."
"The script comes from John D. Payne and Patrick McKay who don't seem to have any widely known previous work to their names."
