When Andrea is in that deserted building (on her way to the prison to warn Rick) hiding from the Governor, remember that creepy tune he whistled as he slowly strolls thru the building?
TIS
I also watched that episode yesterday and thought the same thing when he was whistling that tune. He kind of reminded me of Robert Mitchum's Reverend Harry Powell character in 'The Night Of The Hunter."
Do you remember that movie TIS?
And yes, I too am a bit amazed that no one from this show, be it an actor, actress, writer or producer, has been nominated for any type of award!

Truthfully the actor who played The Governor should have been nominated!
