All they have to do is get the director of Crying Freeman to adapt that movie slightly and you have a great movie.
Crying Freeman was an adaptation of a Japanese Manga, about a man who is captured by a Chinese group of Triads called; Sons of the Dragons.
He is turned into the ultimate killer and they would call him from time to time to dispatch of their rivals.
Now what does that remind me of? Hitman.
Crying Freeman has some awesome fight sanes and star Mark Dacascos. If my spelling is off; sorry Mark.
It is a french made movie and it rocks.
If they mess this movie up, they desevre to be shot. All they have to do is have a back history about number 47, some unbelievably evil enemy and a series of fights in between.
