She said a few days ago that she is "in talks" to play Mrs. Anna. That could mean anything from she's been approached but not formally offered the role; she's been offered the part but is still considering terms; that's she's verbally committed but not yet signed; or even she's signed but the producers have asked her not to comment until they are ready to announce casting. But I'd be very surprised to see the production happen without her.
And someone mentioned Tom Aldredge's 5 nominations without any wins. I'm pretty sure he'll never be nominated again.
