“King Of Killers” (** out of four) was a haphazard action melodrama about a hitman (Alain Moussi) who is part of an international organization of killers (Stephen Dorff, Kevin Grevioux, and others) who are hired to take out the most dangerous criminal in the world (Frank Grillo), only to find out he has turned the tables on them and the hunters are becoming the hunted. Stylish, violent, and absolutely empty although Dorff and Grillo add some spice as usual in minor roles. Similar story told years earlier in “Killer Elite”. Grevioux also wrote and directed.
