 To get the authenticity he wanted, Richard Brooks (I) (qv) filmed  in all the actual locations including the Clutter house (where the  murders took place) and the actual courtroom (6 of the actual jurors  were used). Even Nancy Clutters horse Babe was used in a few  scenes. The actual gallows at the Kansas State Penitentiary were  used for filming the executions, however in a 2002 interview,  Charles McAtee (who was State Corrections Director for Kansas in the  1960s), clarified the hangman in the film was an actor, not the  real deal.
