DiCaprio, 37, will also snort cocaine in his most shocking role to date as former stockbroker Jordan Belfort in the financial crime drama, reported New York Daily News.
"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," a source said.
The plot is based on the memoir by Belfort, which charts his rise and fall as a hard-partying stockbroker who was jailed in 1998 for security fraud and money laundering.
