After firing his whole thief crew and getting a far better one.
Naturally, there's a lot of sex in the movie, mostly between Belfort and his wife (played by Robbie). At one point they even do it on top of a huge pile of money, because a scene where they copulate on a bed full of electric bills and soiled pizza boxes would be too depressingly familiar for most of us.
That money is now worth twice as much from having touched the butts of attractive people.
Behind the scenes, though, things were decidedly unsexy. Sure, life could be worse than being paid to simulate sex with an Oscar-winner and former Growing Pains cast member (as long as his name doesn't contain the words "Kirk" or "Cameron"). It obviously wasn't too bad a deal for Leo either. But for Robbie, the scene had an unintended consequence -- when she got up to get dressed, the crew gasped because her back, they said, was covered in "a thousand red scratches," as if she'd been whipped. Or like she'd been having sex on top of a pack of rabid cats, we guess.
It seems that, while it may look cool (and might be some kind of complex allegory for America), sex on top of money is super unpractical, as it leaves you with more paper cuts than a bloodthirsty Kinko's employee. Robbie definitely didn't recommend it; even the back seat of an antique car on a doomed steamship sounds more comfortable. We should note that, in the interest of journalistic accuracy, we carefully examined every available photo of Robbie taken thereafter and couldn't find any permanent scars, so there's that.
