The assassination was predicted by the 1951 movie The Tall Target
, which was inspired by real events. In the movie, Dick Powell plays a New York police detective, Sgt. John Kennedy, who boards a train to thwart a plot to kill Abraham Lincoln as he makes a pre-inaugural speech in Baltimore in February 1861.
Conspirators on the train know of Kennedy's mission and plan to get him out of the way. One character tells Kennedy, "I don't know anything about a plot against Lincoln's life, but there certainly seems to be one against you." A young man on the train, who has military training, plans to shoot Lincoln through the window of an upper floor of a building as the president-to-be gives a speech from the back of a train car. The assassin will use a rifle with "a new-fangled telescope sight." The John Kennedy in this 1951 film is discovering how the other John Kennedy will be assassinated in 1963.
