The Replacement Killers
The Replacement Killers: Directed by Antoine Fuqua. With Chow Yun-Fat, Mira Sorvino, Michael Rooker, Kenneth Tsang. A troubled hitman seeks aid from a forger to help him get papers to China. However, the drug lord has hired replacements to finish the job, and kill the hitman.
Unbelievably full of cool things, circa 1998: leather trench coats, small caliber guns, slow motion, euro techno, and a hit man on the run for refusing to kill a cop with a family. It’s a little more convoluted than that, but as far as “assassin on the run” movies go, this is a good one.
