Here’s the trailer for Clint Eastwood’s latest biopic, J. Edgar, about the life and career of FBI director J. Edgar Hoover. Leonardo DiCaprio is in the title role with Josh Lucas, Naomi Watts, Armie Hammer and Judi Dench in support. Oh yeah, and Ed Westwick makes an appearance too. DiCaprio is no stranger to playing real life figures on screen, having already played con-man Frank Abagnale Jr. in Catch Me If You Can and Howard Hughes in Martin Scorsese’s The Aviator. As the face of law enforcement in America for almost 50 years, J. Edgar Hoover was feared and admired, reviled and revered. DiCaprio should have fun with this one.
