Yes, and Wizard Of Oz was a movie musical. I'd LOVE Moulin Rouge on Broadway, though it may be hard to top the movie.
I think a Spider-Man musical or a Batman musical would work out great. Shrek can work too, but I don't like the storyline of the film. It's gonna be INTO THE WOODS GONE WRONG.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
