Grey Gardens is a 1975 American documentary film by Albert and David Maysles.
 The film depicts the everyday lives of two reclusive, formerly upper class women, a mother and daughter both named Edith Beale, who lived in poverty at Grey Gardens, a derelict mansion at 3 West End Road in the wealthy Georgica Pond neighborhood of East Hampton, New York.
 The film was screened at the 1976 Cannes Film Festival but was not entered into the main competition.
Phelan Beale Jr. (16 June 1920 – 26 June 1993) was an American journalist and unemployment compensation law expert.
 Beale was a son of Edith Ewing Bouvier Beale and a brother of Edith Bouvier Beale whose lives were highlighted in the documentary "Grey Gardens".
 Beale was a first cousin of Jacqueline Kennedy Onassis and Lee Radziwill.
Grey Gardens is a musical with book by Doug Wright, music by Scott Frankel, and lyrics by Michael Korie, based on the 1975 documentary of the same title about the lives of Edith Ewing Bouvier Beale ("Big Edie") and her daughter Edith Bouvier Beale ("Little Edie") by Albert and David Maysles.
 The Beales were Jacqueline Kennedy's aunt and cousin, respectively.
 Set at Grey Gardens, the Bouviers' mansion in East Hampton, New York, the musical tracks the progression of the two women's lives from their original status as rich and socially polished aristocrats to their eventual largely isolated existence in a home overrun by cats and cited for repeated health code violations.
 However, its more central purpose is to untangle the complicated dynamics of their dysfunctional mother/daughter relationship.
The Cove is a 2009 documentary film directed by Louie Psihoyos which analyzes and questions dolphin hunting practices in Japan.
 It was awarded the Academy Award for Best Documentary Feature in 2010.
 The film is a call to action to halt mass dolphin kills, change Japanese fishing practices, and to inform and educate the public about the risks, and increasing hazard, of mercury poisoning from dolphin meat.
 The film is told from an ocean conservationist's point of view.
 The film highlights the fact that the number of dolphins killed in the Taiji dolphin drive hunting is several times greater than the number of whales killed in the Antarctic, and asserts that 23,000 dolphins and porpoises are killed in Japan every year by the country's whaling industry.
 The migrating dolphins are herded into a cove where they are netted and killed by means of spears and knives over the side of small fishing boats.
 The film argues that dolphin hunting as practiced in Japan is unnecessary and cruel.
