If only people would stop buying tickets to see this musical, it might be adapted for film sooner!! (I have to confess that I just bought tickets to see it my 4th time so I'm part of the problem.)
Stephen Schwartz, composer of the Broadway hit mentioned in an interview at Western Michigan University that a movie version of Wicked is in the works but will be released in about 5 years.
Darn. Hoped for it sooner.
