According to Upcoming Movies , the title has been changed from Man of War to Hostile Act to Hostile Rescue. The release date is currently Jan. 31st, 2003.
Revolution (Sony) picked this one up in turnaround from Uninversal, it's being directed by Antoine Fuqua (Bait, The Replacement Killers, Training Day) and the cast includes Willis, Monica Bellucci and Cole Hauser.
Apparently, it's a "jungle rescue" flick. Could be fun.
