LEONARDO DiCaprio required chiropractic treatment after filming physical scenes for his role in The Wolf Of Wall Street.

DiCaprio stars in Martin Scorsese's latest film as real life stockbroker Jordan Belfort, who lived a hedonistic, drug-fuelled lifestyle while defrauding investors out of millions of dollars.

Belfort became addicted to the sedative Quaaludes, and DiCaprio was determined to portray the effects of the drug accurately during a scene in which the banker has to crawl to a car because he is so intoxicated.

Speaking at the National Board of Review gala in New York City on Tuesday (07Jan14), DiCaprio described his personal coaching sessions with Belfort, saying, "I didn't know anything about Quaaludes, and he (Belfort) had taken a tremendous amount of them. I videotaped him on the floor, rolling around, and he really articulated to me that you have every intention of going to a certain destination, but your body doesn't go along with you. We shot it for, like, a week, and it was a lot of chiropractic work for me because it was incredibly painful."
