I just got back from a screening of the production that was filmed prior to its move to the West End. It was brilliant.
The producers were there. (It was a promo event for the upcoming Broadway run) I spoke to one producer and he said that the cast will be american. I just hope the West End version lives up to the original. ( that is what I saw tonight). I told him that they should just do it in the Circle in the Square. He told me that they thought about it. I now have to see it when it comes as they promised it would be a good production on B'way.
The most thrilling piece of theatre I have seen in a long time.
