Cats- I never once said this was MSG's production. I know VERY well this is not. My reference to "our" was with the production they mounted and toured in the 90s. I just think you are over-reacting.
Further, the RSC Bubble was not like the Wicked bubble at all. They used a golden globe that spun across the stage and into the flies, and then a golden bubble lowered and when it reached the ground revolved to have Glinda sitting.
To the best of my knowledge, the bubble used in Glinda was the first one to have her standing. In most (if not all) she sits on a trapeze that has a bubble frame built around it.
Cassie S has a nice voice, but is one of the worst actresses on this planet.
Cassie S isn't in it. Cassie Olenka, however, is. She was on Legally Blonde: Search for Elle Woods, too, but she wasn't hated by everyone. She just has the same given name.
All I said was that it was similar. Obviously they're not exactly the same. My point though, was that I would not credit Wicked as being the first stage production to have Glinda come and go via a suspended bubble type contraption. Therefore the "familiarity" aspect would be in reverse.
Trapeze vs Standing...not so much similar, unless you mean a bubble shape.
And, to be 100% fair, they are copying the MGM film, which in turn copied a silent film version of "The Little Mermaid" in which the Sea Witch traveled by bubble.
Do we not see eye to eye on anything? I dunno. I thought it looked like a bubble, and I thought the tentacles, though attached to the "round traveling unit" were not meant to actually be a part of it -- they just are because Ursula's costume wouldn't allow for the tentacles to extend the width of the stage.
I remember a while ago I was curious about how the Non Equity tour of Sweeny Todd could have played the Bushnell in Hartford in November and yet come to my small college town of New London next month. I had said that I was under the impression that the Bushnell (The theatre in Hartford)was an equity theatre. And wondered how a tour that is non equity play in an equity theatre. One of the responses to that question was that there aren't equity and non equity touring houses. There are just touring houses that shows can play it. I think that The Theatre at MSG is just a touring house. Not equity or non equity specific.
