Martin Scorsese lets loose with a raunchy comic biopic based on the life of stock broker/scammer Jordan Belfort. Leonardo DiCaprio is the main character, a swaggering money-grubber determined to live high on the hog until the authorities come a-knocking. Booze, drugs, yachts, hookers: Scorsese allows his characters to wallow in this bacchanal of bad behavior. The film doesn't dig all that deep into the roots of this douchebag culture, but it's Scorsese's funniest film, an American tragedy gone entertainingly off the rails. 180 minutes R.
