Tripplehorn adds color to "Grey Gardens"
Jeanne Tripplehorn (HBO's "Big Love") has been cast as Jackie Kennedy Onassis in "Grey Gardens," the true story of two eccentric members of the Kennedy clan.
The HBO Films project, now shooting in Toronto, is inspired by the Maysles brothers' 1975 documentary of the same name.
Jessica Lange and Drew Barrymore already have been cast as "Big Edie" and "Little Edie," the respective aunt and cousin of Onassis, who made headlines when the health department threatened to raid their flea- and raccoon-infested 28-room East Hampton, N.Y., mansion.
Also joining the cast are Daniel Baldwin, who plays Julius Krug, the former secretary of the interior and secret true love of Little Edie; Ken Howard ("Cane") as Big Edie's husband; Malcolm Gets ("Caroline in the City") as Big Edie's accompanist; and Arye Gross ("The Practice") as filmmaker Albert Maysles. Michael Sucsy is directing.
