O brother where art thou
This aging lounge lizard who has the complete trust of druglord LaTour, is actually a class A fuck-up. How he manages to keep his position is a riddle, since the first thing he does in the story, is miss his flight to Haiti, setting off a chain of events resulting in the death of almost everyone involved. While LaTour desperately tries to win time and keep the Rastafaris at bay, Ringo roams hotel bars and casinos, presumably blowing off all the money LaTour gave him.
Never touched by the consequences of his actions, Ringo wins back the money and more, and is finally off to Haiti in the epilogue. It seems Ringo is late for everything.
Bonus info: I originally pictured Harry Dean Stanton in the role of this aging hipster. If the movie ever get's made, I'd go with someone like Mickey Rourke or Val Kilmer. Over-the-hill cool. Someone you would want as your big brother, but you know would fuck up at the first chance given.
