Leonardo DiCaprio Will 'Bare It All' In ‘Wolf Of Wall Street'

Audiences are about to get up close and personal with Leonardo DiCaprio.

The 37-year-old actor will reportedly "bare it all" in Martin Scorsese's "The Wolf of Wall Street," which will follow the rise and fall of hard-partying stockbroker Jordan Belfort, who spent two-years in prison for white collar crimes.

The New York Daily News reports that DiCaprio will take it all off for the cameras, and a source revealed "there will be some pretty illicit sex scenes coming up. It involves four guys and two girls."

The film is also intent on graphically depicting Belfort's drug addiction, with cocaine and Quaaludes playing a big role in the movie -- and the actors are expected to make it look as realistic as possible. "They are asking the actors to get comfortable with snorting baby laxative. They all have to indulge heavily in cocaine," explained the source.

The movie began filming in New York City this past weekend and DiCaprio and co-star Jonah Hill were spotted getting into character by doing some research at Bank of America Merrill Lynch offices at One Bryant Park on Tuesday.

A source at the bank revealed that DiCaprio spent the morning following an employee of the investment bank, while Hill spent his time with someone who works in derivatives.

The film won't be the first time DiCaprio has appeared nude on screen. The actor previously appeared nude in 2008's "Revolutionary Road," directed by his co-star Kate Winslet's then-husband Sam Mendes. In 2010 he told Esquire that he didn't feel weird about the scene because he already knew Kate before she met Mendes.

"So on the outside, it may seem strange to do a sex scene with a woman while her husband is directing. But it didn't feel that way to me," he explained to the magazine. "When the scene was about to start, Kate said, in front of the crew, 'Wait, wait, this is totally weird.' She turned to both Sam and I and said, 'Are you guys okay?' We both looked at each other and said, 'Yeah, we're totally fine.' She said, 'It's even weirder that you're both totally fine.'"
