Summer, 1972: photographer Peter Beard and Jackie O’s socialite sibling Lee Radziwill work together on a film about her relatives and the sisters’ childhood in the Hamptons.

After the project was abandoned, Albert and David Maysles made the 1975 documentary classic Grey Gardens. Lost for decades, this extraordinary footage, which focuses on a vibrant and profoundly influential creative community in Montauk (Long Island) in the 1970s – some shot by Andy Warhol – re-emerges in Göran Hugo Olsson’s fascinating documentary. Olsson uses it as the heart of a hauntingly poignant portrait of the two women, and the many lives they touched.

"Once the film turns itself over to the footage of Big Edie and Little Edie Beale, this movie comes into its own as a fascinating companion piece and prequel to the Maysles Brothers film." - DAN CALLAHAN, THE WRAP
