Not sure if Mayer's flamboyant directing is the right choice for a Chekhov but the cast seems very nice. I saw Annette Bening in King Lear with John Lithgow and she was amazing. Never seen Corey Stoll on stage but he's been attached to many classic adaptations.
My only concern is Treplyov, a difficult character to be played (annoying). I've never heard of the actor who is gonna play him.
