Ian McShane as King Silas in Kings.
This man is absolutely brilliant as the weary King, troubled by signs that he struggle to interpret. McShane's able to bring this complex character to life - lots of grandiose speeches, but he makes all the flowery prose seem powerful and credible. His presence is undeniable, and just controls each scene.
His weathered, lined face is perfect for the role. His purposeful stride is that of royalty. Without speaking a word, he conveys absolute power. The modern, slimming silhouette of his single-button suits don't hurt either.
What a perfect role for McShane. How have I never heard of this incredible actor? It kills me that NBC is canceling this show. The networks have no courage.
