The script has changed quite a bit since the original incarnation of the screenplay adaptation, but word has it that the actual version being used for filming (though still a bit of a work in progress) is much closer to the libretto than previous versions.
Profanity is DEFINITELY still in. I think the only big song that's probably not appearing is Contact. It's so metaphorical that it probably wouldn't translate too easily to film anyway, aside from the subject matter.
I used to hate this movie with everything I had, as a big fan of the show as is, and didn't want it to happen. I had plans to avoid it like the plague, even though I knew I'd end up at least giving it a chance. I saw the shoot on two separate days, and have almost absolute faith that this thing is
going to work.
I wrote two big posts on what I saw if you'd be interested to see them. They're kind of buried. Let me know.
A work of art is an invitation to love.
