I'm sure they can just re-write it to fit him. They just have to make Dr. Bruckner a slovenly shut-in who believes his life is a failure and struggles to write a book and bam! Perfect role for Hoffman.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
I can see the press release (or the intern shill on BWW's boards, whichever comes first): "Philip Seymour Hoffman IS Davey Gamble! He dances across the stage!"
Jordan -- no, he's not in the show nightly. And he's not Connick's standby. Sean Allan Krill is. Hoffman's the standby for the "older guy" parts (the older version of the accompanist, etc)
