I just watched this today, its starring John Cusack, Mira Sorvino (i think?), Hillary Duff (who is awesome in it), Dan Akroyd, and the viceroy is someone I can't place, but he'd famous.
Its John Cusack's second hitman movie, and Grosse Point Blank is one of my all time favs so my expectations were high. But, the movie didn't live up to them.
However thats not to say its a bad movie. its a pretty good one, kind of a commentary on the power of corportions and private military. Its funny, its dramatic, sad, and there is a fair amount of bloodshed. If you have a netflix membership, check it out, its on instant now.
