Lucky Number Slevin/YMMV

• Angst? What Angst?: Justified by Slevin with his "ataraxia". The true reason is of course that Slevin planned all the events of the movie in advance.
  • Although one would think it would be easier to fake being scared than fake a lack of feelings with a gun to one's head. He's also pretty quiet for a guy who is facing off with the men who murdered his parents, and against whom he has orchestrated an elaborate revenge plot. So its likely he DOES have a certain numbness toward his emotions, like his mentor Mr. Goodkat.
• Ear Worm: The Kansas City Shuffle.

It's a blindfold kickback type of game called the Kansas City Shuffle...
