The new DVD is the definitive version of the film: the widely available public domain prints are taken from the hack job done by the film's distributors to keep the running time down. I got a copy of the newly restored one, and it's an entirely different movie in spots.
The London production was downright scary at times because the scenery so overwhelmed the production. They used four gigantic metal towers set on air casters (the only way they could move the weight), and, at one point, an elevator comes from under the stage floor and through a large raked platform -- there was something like 1/16" clearance, and every night the stage manager nearly had a heart attack during that particular scene change.
