Anneliese would be a wonderful choice for Glinda. Samantha is also a great choice for Elphaba, especially since she sung Defying Gravity and received advice about how to sing it from Idina Menzel before she performed it.

Emma would be a good choice for Nessarose, since Nessa is described as a great beauty, which Emma obviously is. Plus not much is required of Nessa vocally, which would work with Emma's voice that is good but not great. Also, her and Daniel Radcliffe in another movie where they're in a school that has a course for teaching magic? I can hear the Harry Potter jokes and references already LOL! I personally was never impressed by Daniel's acting AT ALL but he might surprise me if he was casted as Boq. Aaron would be wonderful as Fiyero!

^That's part of the reason why I want Dan and Em doing another movie together again! Lol.

Sam Barks would be absolutely PERFECT for the role! Her performance in the Les Miserables movie proves such how amazing of an actress she is and just how flawlessly she could pull off the acting aspect of Elphaba. Also, her performance of Defying Gravity on the show I'd Do Anything proves how AMAZING she is at singing and how brilliantly she could pull off the most famous song in Wicked! She's also really beautiful and deserves to be a household name in the United States because of how amazingly talented she is.

Anneliese would be my next choice. This woman would be PERFECT for the role of Glinda! She's a truly MARVELOUS singer, and she's a talented actress as well! Anneliese actually auditioned for Glinda several times on Broadway, but never got the part. How lame is that! She's so talented! Her getting to play Glinda in the movie would be sorta poetic justice and a big "SCREW YOU" to all the Broadway directors who decided against casting her. It's time for her to shine in a big blockbuster so that people will give her the recognition she deserves!
