The Tall Target (1951)

The Tall Target (1951) is a historical film noir crime film starring Dick Powell as a latter-day detective working to foil an assassination plot against then President-Elect Abraham Lincoln.

The action is based on an alleged real life plot to kill the President in 1861, and this historical fact of a possible assassination attempt on Lincoln gives the movie most of its power and interest.

Dick Powell is the star with the period hat and haircut who uses deduction and logic to find who on the train could be conspirators. 

He is straight-up foiled at different times but manages to win the day even when the conspirators have caught him. For effect, the movie's action takes place mostly on the train with the old rocking-camera technique and some fun fights in the steam and in the various parts of the vehicle.
