Silver Shill's voice actor is Ian James Corlett, the father of Claire Corlett, the voice actress of both Sweetie Belle and Little Pony 1. His voice was also modeled after Oscar winning actor Jimmy Stewart.​[​citation needed​]​ His design is unique in that, like some taller ponies such as Mr. Cake, he has a slight underbite. The word "shill" is used to describe a person who poses as a customer in order to decoy others into participating, as at a gambling house, auction, confidence game, etc. It may also be a nod to the shilling, a former unit of British currency.
