I never understand why Wicked comes up in this "impossible for it to work on film" threads, where one its major sources is one of the most succesful movie musicals of all time.
As I've said many times before, if there is one film where singing in random places would be accepted, it would be one that in many ways comes from very well known musical sequences- Wicked.
