According to the festival's website, "Grey Gardens: From East Hampton to Broadway" is 50 minutes long and is directed by Albert Maysles, a co-creator of the famed 1975 "Grey Gardens" documentary that inspired the East Hampton-set musical. (The Oct. 18 screening is in East Hampton, at the UA6 cinemas.)

The picture's producer is listed as East of Doheny (which produced the Broadway show — so don't expect backstage dirt) and Maysles Films. Editors are Conor O'Neill and Sheri Bylander.

According to Hamptons Film Fest notes, "An established cult classic, the film 'Grey Gardens' was released over three decades ago, catapulting Edith and 'Little' Edie Beale into the public spotlight; eccentric relatives of Jacqueline Kennedy Onassis, the Beales were interviewed and filmed in their decaying East Hampton estate by the groundbreaking documentary team the Maysles Brothers. While the film has continued to fascinate cinephiles and documentary lovers, it has moved a step further into mainstream culture with the recent musical adaptation. A success with New York audiences, Grey Gardens won several Tony awards this year, including Best Actress for renowned star Christine Ebersole."

The new pic "now brings the story full circle, as Albert Maysles once again goes behind the camera to interview both the cast and artistic team from the musical and to present never before seen footage from the original film. Examining the history behind the documentary, the cult fan-base around it and the process behind creating the Broadway musical, Maysles captures the public's quirky and undying devotion to the hilarious yet haunting Beales family story."

The screening is Oct. 18 at 7:30 PM at the East Hampton UA6. Tickets are $20. Hamptons International Film Festival runs Oct. 17-21. For ticketing information phone (631) 747-7978 or email [email protected]. Visit www.hamptonsfilmfest.org.
