The late Johnny Hardwick was an indispensable part of King of the Hill, where he became a fan favorite as Hank Hill's conspiracy theorist neighbor Dale Gribble. The lifelong Texan had a keen grasp of the show's premise and served as a writer and producer on the show as well as a voice actor. It's unknown how his loss will affect the upcoming reboot of King of the Hill, but the idea of going forward without Dale -- or Hardwick's irreplaceable take on the character -- is almost inconceivable.
