The world in this film makes the Hamptons backdrop of the ABC soap "Revenge" seem tame by comparison. Maybe Belfort needed to meet a "Nolan Ross", a nerd with some moral concerns and who made his money by creating content, not by manipulating and hucksterizing. To me, Donnie, as a sidekick, wasn't that funny. "Salesmanship" and manipulating others seemed to be the only virtue in this world (other than "drugs" -- of which there are plenty).

Piers Morgan interviewed Jordan Belfort on CNN tonight. Belfort says he lives with remorse, but he denies that, unlike the history with Bernie Madoff, anyone got wiped out. Belfort did say that he was a great father. Does that redeem him?

Lawyer Andrew Greene has filed a lawsuit against Paramount and the principals of this film, demanding it be removed from theaters, details on CNN here. Greene was apparently called by his real name but referred to as "Rugrat" in the film (but "Wigwam" in real life). .
