Hitting DVD and Blu-ray shelves today, J. EDGAR is complex biopic centering on J. EDGAR HOOVER, the man credited with masterminding the FBI and (wrongly or rightly) considered by many one of the most corrupt government official in modern history. Directed by CLINT EASTWOOD from a script by DUSTIN LANCE BLACK, the cast includes LEONARDO DiCAPRIO, ARMIE HAMMER, NAOMI WATTS, JUDI DENCH and JOSH LUCAS.  Stepping into the shoes of this highly complicated historical figure wasn’t easy for DiCAPRIO, who submersed himself in research for the job. During our recent interview, he talked about his biggest challenges. (CLICK ON THE MEDIA BAR FOR AUDIO)
