I am looking for the name of a movie I saw the preview for approximately 2-3 years ago, as my best guess. The movie was based around a hitman or professional assassin, I believe for the mafia, who had a long list of victims and who was notorious for being somewhat of a phantom, never been ID'd, and only seen by those who he was about to kill. However, on one particular job there are two witnesses nearby, a man and woman, in a diner or small shop I think, and they get a look at his face. Somehow they get away and thus, the remainder of the movie is his attempt to track them down so he cannot be identified and remain anonymous. I have no recollection of the actors, I don't think there were any "A-list" appearances. If I remember correctly, the assassin had long dark hair, possibly long enough for a small pony-tail. I hope somewhere in this random description someone can tell me the name of this movie.

Take a look at this list, and you might recognize the name if you see it:

I went through the list and checked all the movies I was unsure about, unfortunately it was not on the list. I appreciate it. This is driving me nuts
