There's more Lincoln in store, and it's lined up at the National Geographic Channel. "Killing Lincoln" is based on Bill O'Reilly's book about the final days of the president and John Wilkes Booth's plot to kill him. Tom Hanks narrates the story as it follows both men leading up to the fateful theater shooting, as well as the ensuing manhunt for Booth--a man who vehemently believed in what he was doing.
