I designed a regional production a few years ago where the director was *very* attached to the Studio 54 revival, and it took a lot of tap-dancing to get him away from it and on his own track. We did have the wall with three doors (I gave him that much), but everything else was this layered collage of 30s German artwork, some painted on the wall, some painted on hanging scrims, all of which gave the stage a vaguely circus-like atmosphere. The emcee's costume had elements of a ringmaster mixed with the traditional tux, but with a seedy overlay to it all by some odd detailing. (Our costumes, BTW, were more along the lines of the original production than the revival, but much seedier and lower-class -- we took the approach that this was the German equivalent of a blue-collar honky-tonk)
When it came time for the end, we did the trick of having the orchestra pre-recorded so they could make an invisible exit before the emcee's final speech, but we went one better: our acting company was now on the upper level, in virtual down light. No costume changes, just this very strange greyish light. Then, as the wall itself began to rise, we had all this strong side lighting at deck level that trapped the emcee while two spotlight operators let their lights wander all over the stage.
By now, the wall had cleared the scaffolding, and the company, like the orchestra was gone. Just the emcee, trapped in his lights. It was very, very cool. Not a single swastika on stage, but none was needed.
