Evoking the style and pace of the Noir genre, the film is essentially a murder mystery with Stanley (Gareth Reeves) the prime suspect. Stanley's success as a novelist has been largely due to his style where he writes from the first person perspective of the central characters, who are always the killers in real-life cases. Troubled with writer's block, his agent suggests a tramping trip "to clear his mind". However, when he wakes up on the first morning of his tramp, he finds his fellow tramper dead.
Unfortunately the movie I'm Not Harry Jenson is not yet available on HBO Max.
