Oh that's awesome man, I wish I could have seen it.
The casting sounds great.
How was the acting, if you don't mind me asking?
I just re-read it with those actors in mind and I can imagine Michael Stuhlbarg, Zeljko Ivanek and even Goldblum being perfect for their roles.
I only know Billy Crudup from Public Enemies but I hope he did well as Katurian.
As for Pinter, I haven't read any of his work but I'll have a look at it sometime.
