I don't know WHY people are suggesting Rob Marshall. His movies are a miz of art, sexuality, and style. Wicked requires fantasy, magic, and SFX. Rob Marshall would be a terrible choice for Wicked. His talents are Great for Chicago, Nine, and maybe other musicals like Cabaret, Sweet Charity and other projects in that category of musicals.
Tim Burton is great for Fantasy, Magic, and lots of SFX, but he also is very dark, and that will not fly for Wicked. Wicked DOES need an element of darkness, but not to the level of Tim Burton's taste.
A great directorr for Wicked, IMO, would be the Chris Columbus. He did a terrible job for Rent (even though rent is not a show meant for the screen by ANY director, imo), but think of the Justice he did for his Harry Potter movies. The way he told the sentimental story mixed with the fantasy elements was excellent. As long as the script is well written (because Rent's was garbage) he'll be great.
