Using Snowflake's list:
Eva Mendes ... Crystal Allen - no idea who EM is...
Meg Ryan ... Mary Haines - WTF X2. Meg Ryan... she's all gums when she smiles. Can't stand her.
Carrie Fisher ... Nancy Blake - I actally like this casting. It could have been Lilly Tomlin, too.

Candice Bergen ... Catherine Frazier - Who the heck is Catherine Frazier?
Jada Pinkett Smith ... Miriam Aarons - No. JPS looks like she's mad all the time. Miriam should have been someone hotter and nicer.
Debra Messing ... Edith Potter - Really?! No no no no. Edith should have been played by someone feisty who can act.
Annette Bening ... Sylvia Fowler - Foul indeed. UGH! Can't stand Bening. I only liked her in
American Beauty. We'll see what she does wit this cherry of a role.
Bette Midler ... Flora DeLave - That could work... But Every movie that Midler had been in lately has tanked. She's bad luck or something.
Cloris Leachman ... Maggie - I love her.
Debi Mazar ... Olga - I could see that.
Keegan Connor Tracy ... Dolly Dupuyster - No idea.
Joanna Gleason ... Barbara Delacorte - Not sure who she is...
All of this makes me sad. But at least the original is still there for all of us to enjoy.
More to add...
I just looked at the pictures.
Canoes?!
And Dianne English has never directed before. Can she do it?
