Academy Award-nominated director Oren Jacoby helmed this documentary adaptation of former Catholic priest James Carroll's nonfiction book of the same name. An anti-war activist, Carroll delves into Christianity's history to learn how a faith founded on peace could come to be used as a tool for war-mongers. Jacoby follows Carroll as he explores the phenomenon from its origins in ancient times up through the modern-day U.S. military. Constantine's Sword screened at the 2007 Los Angeles Film Festival. ~ Matthew Tobey, Rovi
