It was Pam Gems' adaptation, so not the full text, and I think it was heavily altered. I think the original play is pretty well unperformable as a straight play - it's written more like a dream, and I saw it in a proscenium arch theatre, when it would have been much better in a theatre-in-the-round type space, more intimate.

Out of curiosity, how was the trial (if it was shown onstage) handled? If it's in there, I'd imagine it's hard to do convincingly...
