Martin Scorsese's financial drama sees Leonardo DiCaprio snort cocaine and partake in an orgy.
The 'J. Edgar' actor is set to strip off and snort cocaine in his most shocking role to date as former stockbroker Jordan Belfort in Martin Scorsese's financial crime drama.
A source told The New York Daily News newspaper: ''There will be some pretty illicit sex scenes coming up. It involves four guys and two girls.''
''Leo has a scene coming up where he is completely out of his mind on DRUGS with the other brokers. Cocaine and Quaaludes will be a big part of the movie.
''They are asking the actors to get comfortable with snorting baby laxative. They all have to indulge heavily in cocaine.''
The plot is based on the memoir by Jordan Belfort, which charts his rise and fall as a hard-partying stockbroker who was jailed in 1998 for security fraud and money laundering.
The film will involve a lot of nudity as Leonardo indulges in an extreme party lifestyle, and the crew are currently casting for women who are will to strip off on screen.
The insider added: ''We have a scene in an office with a troupe of hookers during a coffee break.
''They are in the process of casting a ton of beautiful models, who are willing to bare it all, to portray escorts and strippers.
''The girls have to be incredibly hot.''
Martin and Leonardo have been championing the project since 2007, after having previously worked together on 'Gangs of New York', 'The Aviator', 'The Departed' and 'Shutter Island'.
The film begun shooting in New York's Financial District last weekend (25.08.12) and is scheduled for release in 2013.
