Who is Big Mack? (2007)

At the start of the dark-comedy film, Willie is bound and gagged by two mafia hit men and brought to a bar where he is tied up to a stool. He's told they must wait for 'Big Mack', the head mafia boss to show up. They leave Willie with a flunky named Crunch, who they have no respect for, and go out for a coffee. We learn from Crunch speaking with Willie that Willie and his brother stole money from Mack last night. Crunch implores Willie to give up his brother to save his own life - Meanwhile the subject of who Mack really is comes up. Nobody has ever seen him, but the stories are rampant. "He killed a man with his bare hands". "I almost met him once but just missed him". - It all ends with a wild twist that pulls the rug out from under the viewer.
