The producers of KINKY BOOTS would be extremely foolish to petition the Administration Committee to place Billy Porter in the Leading category. He would not win and stands lesser a chance to be nominated -- especially since Stark Sands is sure to be placed there, regardless of Porter's placement.
The competition in the Featured category is quite small. The only two stand-outs are Bertie Carvel and Billy Porter. Other nominees could be Gabriel Ebert, Will Chase, and 1 or more from HANDS ON A HARDBODY. I doubt anyone from ANNIE, SCANDALOUS, MOTOWN, CINDERELLA, CHAPLIN, BRING IT ON, or A CHRISTMAS STORY will get a nom here. I'm unfamiliar with JEKYLL & HYDE and PIPPIN, perhaps they have contenders that I am not factoring in.
"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."
