Proudest of which film?

I thought she once said in an interview that Tootsie was the film she was proudest of. As for which film she regrets most I honestly couldn't say. Everyone loves to razz on Hush but Jessica was fabulous in it. For some reason it reminded me a bit of Die, Die My Darling! starring Tallulah Bankhead and Stefanie Powers. Admittedly, it wasn't a perfect film, but Tallulah was divine in it; her performance alone more than compensated for the films imperfections, and I feel the same way about Jessica's performance in Hush.

Same here. The film left much to be desired even as a simple thriller, but Lange gave us quite a complex, multi faceted character to enjoy and ponder for years. The same could be said for A Thousand Acres. Really poorly put together film but Lange (and Pfeiffer, Robards) gave Oscar worthy performances.
To me, Frances is her magnum opus. However, I do find Music Box to be my personal favorite.
My least fave: Country. I'm sorry, I just can't bother with that film.

What did you think of Lange's performance in "Country"?

For me, I thought that her performance was strong in COUNTRY, although I did not really enjoy the film overall. It was just too much of a downer from what I recall. I haven't seen it since its theatrical release back in the 80's.

I haven't seen "Die, Die My Darling," but I must admit that HUSH is a guilty pleasure. I didn't think it was all that bad. I even saw the version with the original ending. I kick myself for returning the VHS screening copy long ago. IMO, the original ending was far superior. In it, Jess's character dies in a barn blaze.

Dimsung, I thought it was good, no more no less. It was a weak year for actresses that year otherwise she wouldn't have earned her Oscar nomination imo. I don't know maybe in comparison to her level of greatness that we'd seen it doesn't even come close (hell she gave better, memorable character performances in such duds as Hush, A Thousand Acres and Cousin Bette), so to me Country was not one of her greats.
