The story of the film stems from the failed attempt of Academy Award-winning actor Tom Hanks and producer Gary Goetzman to make Vincent Bugliosi's mammoth book about the Kennedy assassination, Reclaiming History, into a miniseries. He exposes the questionable origins of Reclaiming History in a dubious mock trial for cable television, in which Bugliosi played the role of an attorney prosecuting Lee Harvey Oswald for murder, and how this formed the basis for the epic tome.
JFK: The Evidence Today lists the myriad problems with Bugliosi's book and explores the cooperation of the mainstream press in concealing many facts during the publicity campaign for the book and how this lack of scrutiny led Hanks and Goetzman-cofounders of the production company Playtone-to purchase the film rights. DiEugenio then shows how the failed film adapted from that book, entitled Parkland, does not resemble Bugliosi's book and examines why.
It includes an extended look at the little-known aspects of the lives and careers of Bugliosi, Hanks, and Goetzman. JFK: The Evidence Today sheds light on the Kennedy assassination, New Hollywood, and political influence on media in America.
