I'd love Tina Fey to be involved, but I don't know that she needs to necessarily reprise her role in the film, nor would she really want to, I'm sure, with her busy schedule.
I'd love to see the cast winter_sky and I had planned out, Norm Lewis would be hysterical.
And I can just see Jessica Lee Goldyn delivering lines like "So, you think you're really pretty?" and "That is the ugliest effing skirt I've ever seen." so flawlessly.
If The Devil Wears Prada is musicalized, the Streep character SHOULD NOT sing until that scene in Paris. There's no reason for her to sing before that moment. I think it could make a fairly good musical though. And I think Mean Girls would make a god awful musical. It was a charming film. Can't we just leave well enough alone?
I was actually thinking Sierra Boggess as Cady, but then when I read Annaliese Van Der Pol, I changed my mind. The funny thing is, I could actually see Annaliese as Andy Sachs in Prada too!
