Directed by acclaimed Swedish filmmaker Göran Hugo Olsson, That Summer centres on the film project artist Peter Beard initiated together with the incandescent Lee Radziwill about her relatives: the Beales of Grey Gardens. Lost for decades, this extraordinary footage re-emerges in Olsson’s documentary, which focuses on Peter Beard and his family of friends, who formed a vibrant and profoundly influential creative community in Montauk (Long Island) in the 1970s. Featuring Peter Beard, Lee Radziwill, Edith Ewing Bouvier Beale, Edith Bouvier Beale (Little Edie and Big Edie), Andy Warhol.
