Following his standout job playing two roles, Dominic Cooper has booked one really big gig.Cooper starred in this summer's Iraqi war drama, "The Devil's Double," playing both Saddam Hussein's psychotic son Uday and his body double, Latif Yahia. At one moment blustery, irrational and maniacal and then subtle, pained and just, the role won him major plaudits and put him on the leading man radar screen of some of Hollywood's top directors.
