The 31-year-old actor slowly fell "in love with movies and the idea of the process of making films" growing up while watching his parents, who worked as a 1st AD and sound recordist. After grinding for 10 years and studying drama in college, Montgomery eventually landed his breakout role as Billy in Stranger Things in 2017.
