Then watch this HBO production; and you will appreciate even more how brilliant and uncanny Jessica Lange is as "Big Edie." It's almost supernatural to watch her capture the essence and spirit of Big Edie. This is no mere performance; she totally inhabits the woman; she becomes her (watch the "Tea for Two" number and be amazed!). And this isn't the first time Lange pulls that off; she does it with Patsy Cline and Francis Farmer. At this point in her career, you expect Lange to be brilliant - and from Francis (ok, I may be in the minority here, but I even liked her in King Kong; I knew there was more there than what we were seeing in that film) through AHS: Freak Show - well, she is amazing. And I look forward to seeing her in O'Neill's "Long Days Journey Into Night" in May on Broadway.
But the real revelation here, for me anyway, is Barrymore. Nothing, NOTHING, she has done previously will prepare you for what she does in this film. She is miraculous. Again, only if you watch the original documentary can you appreciate how Barrymore inhabits this character completely; from the voice, to the costumes, to the mannerisms. For me anyway, this performance came out of nowhere. She is brilliant.
I can never argue with Lange winning an Emmy but If there was ever a time when it should have been a tie, this was it. And since it did come down to either/or, I personally would have gone with Barrymore. Not because she's necessarily "better" than Lange, but simply because her's is the most surprisingly astounding performance.
I can't recommend both "Grey Gardens" enough.
