James Rado worked closely with the production which is currently running in Toronto, in fact, he was there the night I saw it. I'm not sure what he did to 'update' it, if anything, it didn't seem at all 'modernized' to me, from what I know of the story.
There was nudity in the opening scene and again, in the usual, scene which closes Act I. There was definitely no scrim, the lights were in no way dimmed, and the entire cast was there in all their respective glory.
The show has some flaws, which may possibly be inherent, not sure, but it is a very enjoyable evening of theatre, and a talented cast. The audiences have been loving it, with most shows running at 100% attendance, which is predicted for the entire three month run.
