Before I even clicked on the link I immediately thought of Toni Collette. Speaking of The Wild Party. You could even bring back her pairing with Tonya Pinkins for Vera.
Just for any one that's interested there is a small revival in UK later this year.
This theatre has been producing some work to critical acclaim and currently has a striped back version of Aspects of Love transferred to the off West End Southwark Playhouse.
I think Donna Murphy would be superb. Emma Thompson is an interesting suggestion. I also think Christine Ebersole would be terrific. I think Laura Benanti and Sutton Foster still come across as too young for the role in persona but would obviously have the acting/vocal chops to pull it off.
