I agree with the article, I don't think Ewan McGregor is an ideal choice for Guido. I really would love to see Krakowski in this, just because she's one of my favorite actresses, but I know it won't happen.
In the meantime, I disagree about the comparison between adapting NINE and SUNSET BOULEVARD to film. The book for NINE is in the style of 8 1/2 and the plot is similar but I think that what Tommy Tune, Arthur Korpit, and Maury Yeston did was fantastic, they borrowed Fellinni's style and still managed to make a show that a completely separate entity from the film (which is what 99% percent of movie-to-musical adaptations have failed to do). SUNSET BOULEVARD uses some text that is taken straight from Wilder's script and doesn't really alter the adaptation in the way that NINE does. The movie will need a great screenwriter to succeed though...Bill Condon where are thou?
