My wife and I caught Ms. Turner in this play when it was in London. It was quite plodding, Turner was the only decent Actor/Actress in the production and it borrowed heavily from the movie (Turner had manerisms much like Bancroft in the original). I thought it was played to a kind of a "campy" effect.
Oh yes, the nude scene...it was so dark you could only see a silhouette, but it was a very attractive silhouette!
sigh...
