WOW - I have just read through all the 8 pages of this thread!
As I have seen the show only in London ( once with Betty Buckley and John Barrowman and another time with Elaine Paige and also John Barrowman) I thought I would not have anything to say as the subject was supposedly comparisons of changes in the various productions. Little did I know that so much discussion has transpired on many aspects of the musical and the many productions.
This is my second favourite ALWebber show ( Aspects of Love being my top choice) and I have always loved revisiting the score. I have also enjoyed the original source material, the film noir classic from Billy Wilder with William Holden and Gloria Swanson.
May I share a few more facts/some buzz not yet mentioned --
*Michael Ball was the first to sing the songs of Joe Gillis when the musical score, first version, was premiered in the Lloyd Webber estate, Sydmonton, where ALW normally stages his new work ( mainly singing the parts). It was Michael who released the first version of the title song at the instance of ALW, before the cast recording of the London production was released in London.
*Michael, although rumoured for the original cast, never played the role onstage. Many years later, he sang the role in a semi-staged concert version in Cork, Ireland, with Petula Clark and Emma Williams ( original Truly in Chitty). As this concert was BBC-sponsored, it was broadcast on BBC Radio 2 ( and played for sometime under its LISTEN AGAIN facility). It is also interesting to note that he has the only male recording of WITH ONE LOOK ( in his musical album called THE MUSICALS), saying that it is an actor's song!
*The Broadway production continues to hold the highest advance in Broadway history at $ 37 million. Please correct me if this has been recently broken, though.
*The Australian production, plagued by a number of problems, never did get a cast recording. But an hour-long documentary was shown on Aussie TV and featured how the show was shaped into being ( casting, rehearsals, set construction, costumes, etc), including clips from the show, interviews with Debra, Hugh, and Trevor Nunn, and clips of some of the songs sung at the show and in rehearsal. One offshoot of the teaming of Debra and Hugh is a reprise of their collaboration, via a two-song medley sung as a duet in Debra's CD New Ways to Dream ( No One is Alone/Children Will Listen from Into the Woods). Another offshoot of this production was the eventual casting by Trevor Nunn of Hugh Jackman in the Royal National Theatre's OKLAHOMA! in London.
*RUG has announced that a film version will be made, but it seems to be in limbo at the moment. The buzz is that while Paramount Pictures has given approval of the rights to film it ( they own the rights to the original Billy Wilder movie), it seems that the studio does not want to be involved in financing it ( leaving it to ALW to pursue the financing). The last time ALW said something about the project( sometime this year) was to mention that he might be casting Hugh for the movie version. But that rumour has been there for sometime, so who knows?
*Someone has mentioned that this seems to be Joe's Story rather than Norma Desmond. Well, he does narrate the story ( from the dead

)...Also, in the original movie, the name of William Holden preceded that of Gloria Swanson in the billing.
I am hoping that given the timing of many movie musicals now, that Sunset Boulevard will finally find its musicalized version on screen. It would be a very interesting subject to the movie-making industry - as it is really an indictment on Hollywood, in that particular era of movie-making
