NEW YORK: Leonardo DiCaprio is suffering from an injury he sustained while shooting The Wolf of Wall Street. The actor spent a week shooting a scene in which his character tumbles down stone steps while high on Quaaludes and is now suffering severe back pain . “He says he’s in nonstop pain and has gained weight because he can’t exercise,” reveals a source. “It hurts to lie down for too long, and it’s agony to twist his body into any crazy positions. “He considers it the role of a lifetime. Of course, it would ease the pain if he won an Oscar”.–SS
