So, for the joy of resurrecting old threads I figured I'd put this post here.
I just watched Seven Psychopaths, and there is a scene where one of the psychopaths is telling his story where he and his lady killed some people back in the day. One of the clips is where they do in the Phantom Killer in Texarkana! I actually missed the very beginning initially where they say "Texarkana Moonlight Murderer" on the screen. I just saw the Phnatom pop up in the back seat of a 1940's car and they dump gasoline on him, cut off his arm and torch him - I was like "wait a sec, that guy looks awfully familiar!"
