The Drowning Pool is the second film featuring private eye Lew Harper (Paul Newman), following the 1966 film Harper. This time around Harper is called to New Orleans to investigate the blackmail plot involving a former flame, Iris Devereaux (Joanne Woodward). She has received letters threatening to expose embarrassing charges of marital infidelities and she wants Harper get to the bottom of it. Things get complicated quickly when he gets roughed up by local cops working under Chief Broussard (Tony Franciosa). Apparently they want Harper to stay off this case, which involves Devereaux's nymphomaniac daughter Schuyler (Melanie Griffith), a rich oil tycoon, Kilbourne (Murray Hamilton), and Kilbourne's wife Mavis (Gail Strickland). Eventually the quick-witted Harper faces death in a room slowly filling up with water, the "drowning pool" of the title. This 1975 followup was directed by Stuart Rosenberg, from a screenplay by Tracy Keenan Wynn, Lorenzo Semple, Jr. and Walter Hill.
