Characterization
Noah Schnapp was cast as Will Byers in August 2015. Schnapp was promoted to series regular for the second season in October 2016. Schnapp was revealed to be returning for the third season in a main role by February 9, 2018. The idea of having Will communicate with Joyce via lightbulbs was inspired by 1980s films, including Poltergeist. In terms of the narrative in the third season, Levy said the season would be less about Will, saying, "We're not going to put Will through hell for a third season in a row. He'll be dealing with stuff, but he won't be at rock bottom... We're [going to be] dealing with forces of evil that are new."
