^ Biggest surprise in this interview: physical comedy segment wasn't planned. Yet for me it felt very deliberate.
Speeches delivered by Belfort didn't convince me either, but should they? This reminds me of "Nashville", where most singers were more than average. What is import here I think is abuse of confidence and trust. I'm not only speaking about clients, but also about workers. He gives very graphical presentation of the script to his workers and they are laughing their asses off, probably thinking about those poor suckers. Yet his "friends" from Wall Street are swallowing his IPO/quitting pitches without a problem. In the end he sells them to FBI.
Everything is for sale and everyone can be bought - this is pretty much a Jordan attitude. Notice how upset he gets, when this doesn't work. FBI agent is obvious example. There is also Duchess - that sex scene was like a message "I paid with my body for last time, leave me alone" for me and then he goes for drugs as he figures out that she bought him, not the other way around. He initially gets very angry with article in Forbes - they didn't buy his fairy tale about Stratton Oakmont.
