Just hours before his death, John F. Kennedy appeared before a crowd in Fort Worth, Texas to honor the freedoms of America in what would be his final speech. Though the Zapruder film, a silent, 8mm home movie of the presidential motorcade through Dealey Plaza, is the most complete visual recording of JFK s assassination, it is just part of a vast record of sights and sounds captured on camera that day. This four-hour special from HISTORYTM uses unique, rarely seen and heard footage to document the Kennedy assassination and the nearly 50 years of speculation and controversy that changed America.
