I recently re-watched the Original Series episode The Conscience of the King in which Kirk must discover if the leader of a traveling actor troop is in reality a mass murderer who has escape justice.

As indicated by the title taken from Hamlet the scrip has numerous references to the Bard and his works but on this viewing I was taken by just how much the episode leaned into the conventions of film noir.

The story’s spine is a mystery with Kirk playing the role of the detective, searching for clues amongst a forest of lies and deception. He is enamored by a mysterious beauty who ultimately proves to be quite lethal a near perfect femme fatale. The obvious answer to the mystery turns out to be only near correct with a final act twist that reveals a darker and more tragic answer to the series of murders.

In addition to the thematic and plot elements that line up so perfectly with noir that series, though still displaying the bright television set selling colors, Finnerman the director of photography still manages to utilize shadow through the episode giving it a darker image befitting the story.

In my opinion there is no doubt that Star Trek’s The Conscience of the King is film noir.
