I posted this question on Twitter. Considering that I have only half a milliwheaton of followers, it's done well. So I've decided to open it up to the larger Neatorama community.
I no longer watch Game of Thrones. After viewing the episode "The Mountain and the Viper," I decided that the show is so dark that I don't want it in my head anymore. But I won't dispute that it's an excellent program and that Peter Dinklage, the actor who portrays Tyrion Lannister, is a master of his craft. This was particularly evident in that same episode during the scene in which Tyrion and Jaime discuss their relative Orson Lannister.
Dinklage has experience on the Shakespearean stage. He portrayed the titular character in Richard III. In what other roles by the Bard would he do well? I can see him as the volatile, wisecracking Mercutio in Romeo and Juliet or the scheming, vengeful Edmund in King Lear.
What do you think? What Shakespeare character would be best for Peter Dinklage?
