I would love her as Catherine in "Suddenly Last Summer"! In the Williams vein, why not Alma in "Summer and Smoke", or Marguerite in "Camino Real"? Princess in "Sweet Bird of Youth" is actually picture perfect casting - can you imagine the depths of the first act contrasted with the deluded self-assurance of the third?
She'd also be interesting in "Hedda Gabler" or "A Doll's House". Is she too old for Irina in "Three Sisters" and "The Seagull"'s Nina?
Hell, she might even make "Tiny Alice" a hit if she plays Miss Alice.
