PiraguaGuy - on stage, an older actress playing Little Sally works. IMO, on film, it'd have to be a young girl and the humor changes. At least that's what I would do if I were helming a film adaptation.
"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."
