I saw the first preview of "South Pacific," then saw it a number of times after it opened (including the very final performance). There were a lot of changes after that first preview, and even though I loved that first preview, it clearly improved from there. BTW, the only actor I thought was totally in the pocket from that first preview on was Danny Burstein as Billis. It took some of the others a while to find their footing.
The King & I is substantially better now than when it opened, with Hoon Lee as the king. I saw it again a few weeks ago and was transported (though I still don't get the hubbub over the big boat in the beginning -- maybe it's more impressive depending on where you sit?).
I saw Fiddler on Tuesday night, and because there are more than two dozen performances between now and opening, I feel certain, based on the experience of seeing mulitple performances of SP and K&I, that this show will be substantially different when it officially opens.
I'm not a theater person -- I didn't see my first Broadway show til I was 24 years old -- that is one of the reasons why when I see something great, even if imperfect, I try to go back again (and sometimes again and again) to study the show and see why it works better down the line.
I saw SP so many times that I almost went broke (wait, I did go broke -- I'm still in debt) -- but it was thrilling to watch all three Emile DeBecques (Paolo Szot, William Michaels, and David Pittsinger -- all very different, all brilliant) and watch how Kelli (and then Laura Osnes) adjusted their performances based on who was singing the lead that performance. I started to think of the three Emiles as the three Billys in Billy Elliot -- didn't matter who had the part that night; the audience was in for a treat no matter what.
It's been fascinating reading all these comments -- pro and con -- if nothing else, for sure I am going back again after Fiddler opens -- I have to do it for my own education, no matter what it does to my bank account. But I'm curious about rush tickets (don't know how that works -- I'll have to study up on that).
Maybe my theater addiction won't automatically lead to bankruptcy?
