Yes, Scorsese has always entertained us so well with abberant types, from mobsters to street criminals to boiler room stock brokers, all dealing death or financial destruction 24/7. But, do any of them bear even a faint resemblance to what really happened, and did those people actually behave that way? Regarding this film, I worked on Wall Street during that time, and even though we had heard of Jordan Belfort's firm, it was totally discounted as a boiler room and had no Street cred at all, just a terrible rep as sleazebag junk. It was no more than a side story to the real Wall Street, as those boiler room types were the lowest level of that era's greed-is-good WS slicksters.
But, the movie.....could any human superman take the amount of drugs and unprotected sex shown in this story and even function, let alone at a high continuous level and not have a fatal heart attack? None that I have known or seen, and I have seen a lot. But, Dicaprio as Belfort was a marvelous choice for this outsized role, and he played it to the hilt as never before, with Jonah Hill as his sidekick comic relief, and Matthew Macconaughey a great choice for Belfort's oddball, probably whacked out(off?)mentor, and Bob DeNiro in a short mobster spot.
It was such fast action that the 3 hours went by quickly, with not a dull moment in it. I enjoyed the fantasy ride that Disney could not have done better, but I could never get past the fact that it was 99% dramatized fiction, done to sell tickets(greed is good!) but not to enlighten us at all about the real Wall Street of that era.
