The U.S. presidential election may be three years away, but speculation is already rife about the runners and riders in what is sure to be an epic battle for the White House.

Some of the fiercest debate has emerged not from the corridors of power in Washington but from Hollywood in the shape of a planned biopic, "Rodham."

The movie will portray a thinly fictionalized version of a young Hillary Rodham starting out on a life path that should, according to observers, see her, as Hillary Rodham Clinton, being the overwhelming favorite in the 2016 contest.
