Old Bill is a minor character in the first season of Westworld. One of the first hosts built. Now decommissioned and stored on Sub-Level B83, Bill is still visited from time to time by the Park Director, Dr. Robert Ford. Bill is played by Michael Wincott.
- "The Original": Bernard Lowe and Ashley Stubbs find the disturbance in Sub-Level B83 is actually Dr. Robert Ford who's turned on one of the old hosts for a personal discussion. Old Bill is eager to toast the lady with the white shoes, but Ford turns him off and asks that the host put himself away, and back into storage.
- "Contrapasso": Dr Robert Ford visits Old Bill again and has a drink with him. Despite Ford leading him, Old Bill sticks to his pre-programmed script throughout the conversation; he's not able to do anything else.
As an outmoded first-generation Host, Bill's personality seems to be limited. His only appearances involve him pouring and conversing over drinks; presumably this was part of his narrative when he was still in the park. He appears to be amiable and friendly to Ford, or perhaps, to whomever shares a drink with him.
His tone is wistful and somewhat detached. He'll listen intently to stories that another person tells him, but only remarks that the story is "a real humdinger," indicating that his listening, comprehension, and improvisation abilities are too primitive for anything else.
