This pilot film for the TV series Harry-O was originally telecast under the title Smile, Jenny, You're Dead. David Janssen plays Harry Orwell, a seedy private eye investigating the murder of his friend's son-in-law. The principal suspect is the victim's wife Jenny (Andrea Marcovicci), a photographer's model. Since this is less a mystery than a suspense story, it isn't unfair to reveal that the real killer is a looney photographer (Zalman King, later a prolific producer of film erotica!), who is in love with Jenny and insanely jealous of anyone who gets in his way. The climax takes place on the roof of a high-rise. Guess what happens. The Harry-O series proper debuted in the fall of 1974, lasting two seasons.
