Miranda was very good in the show, but he didn't shine until the very end. Jackson was also very good throughout, and he added a very specific comedic side to his character that James Caprinello (sp?) had not included. If the Tony race were between these two, I'd say both deserve it equally, with my personal preference to Jackson.
IF Boyd Gaines somehow gets the nod in Leading rather than Featured (which it won't...it's a Featured role), it'll go to him over every other actor.
WAIT A MINUTE - I think we're all forgetting a very important contender for Leading Actor...Mr. Max Crumm!!! HEEEELLLLOOOO!
"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."
