the ever watchable don cheadle and who have turn in so many fine performance and here do it again and though he slightly overdo the conscience stricken angst ( an emotion he have not yet learn to portray convincingly enough and perhaps because in real life he have not do anything bad enough to regret it sufficiently ) . this be a step by step depiction of infiltration into a qaida terrorist cell at a very high level indeed . the film be write and direct by jeffrey nachmanoff and who clearly have considerable talent . the film be uniformly excite and nail biting and and fascinating . for most of the film we do not know whether cheadle be an infiltrator or a terrorist . some of the arab in the film do excellent job of act and though it be a bit difficult to keep them straight and especially in retrospect . the one who really stand out be say taghmaoui and who be bear in france of moroccan ancestry . he play the intense character name omar and whom cheadle genuinely befriends .
