'The Bourne Supremacy' and 'Bloody Sunday' director Paul Greengrass is to write and direct 'They Marched Into Sunlight', an adaptation of the Vietnam War-era book by Pulitzer Prize winner David Maraniss.
Variety reports that Maraniss' non-fiction book intertwines narratives about US soldiers ambushed in Vietnam, anti-war protests on a Wisconsin campus and the confusion and behaviour of officials in Washington.
Greengrass is also set to direct the big screen version of Alan Moore's acclaimed comic series 'Watchmen'.
