I see IN THE HEIGHTS working better as a made-for-television movie. A feature would work as well. We know already that Jennifer Lopez wants to be in it. Antonio Banderes would work as the father...but I don't think it is a role he would want.
WICKED has been in the planning stages forever. It'll happen when they need to boost the sales of the Broadway show to keep it alive. They'll get really big names for it, obviously.
"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."
