Wow, I probably never would have thought of this, but now that she's been cast it makes sense: Jeanne Tripplehorn, known mostly for her role on Big Love, will play Jackie O in HBO Films' production Grey Gardens.
Based on a 1975 documentary, the story follows Big Edie and Little Edie (played by Jessica Lange and Drew Barrymore, respectively), the "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."
I am always drawn in by Tripplehorn's performances on Big Love and I'm curious to see what she does with this role. Like any movie character based on a high-profile public figure (Idi Amin, Queen Elizabeth II, etc.), it's a pretty tall order.
