The Drowning Pool is a 1975 American thriller film directed by Stuart Rosenberg, and based upon Ross Macdonald's novel The Drowning Pool. The film stars Paul Newman, Joanne Woodward, and Anthony Franciosa, and is a sequel to Harper. The setting is shifted from California to Louisiana.
Private detective Lew Harper (Paul Newman) investigates a blackmail plot in Louisiana bayou country involving the nymphomaniac daughter (Melanie Griffith) of an old flame of his, Iris Devereaux (Joanne Woodward). He is caught up in a power struggle between Iris and oil tycoon Kilbourne (Murray Hamilton). At one point, the complicated plot has Harper and Kilbourne's wife Mavis (Gail Strickland) locked in a hydrotherapy room, with the water rising to the ceiling, hence the film's title.
The Drowning Pool was released on November 14, 2006 as part of the Paul Newman Collection DVD box set.
