Back in 1975, Albert and David Maysles, Susan Froemke, Ellen Hovde, and Muffie Meyer made a documentary about the lives of Edith "Big Edie" Ewing Bouvier Beale and her daughter Edith "Little Edie" Bouvier Beale. They were the aunt and cousin to Onassis and lived a bizarre life in almost total isolation in a ramshackle mansion by the name of Grey Gardens. After trying for years to have the home brought up to code, the two were finally separated when "Big Edie" died in 1977 (Little Edie finally sold the house in 1979 to a former editor for the Washington Post). The documentary inspired an award winning stage musical in 2006 starring Christine Ebersol as Little Edie. The new film from HBO will not be a musical (thankfully, I might add) and instead was based on the original documentary.
The cast also includes Daniel Baldwin as Julius Krug, the former secretary of the interior and true love of Little Edie (Barrymore). Tripplehorn is doing some post-production work for Winged Creatures, an ensemble drama about a group of people who survive a shooting in an L.A. diner (I guess it will be kind of like Crash, but with more gunfire). Grey Gardens is being directed by Michael Sucsy (who also co-wrote the script with Patricia Rozema) and is currently shooting on location in Toronto, Canada. Grey Gardens will hit theaters in 2008.
