First series thread Second series thread Press Release: Casting (per Deadline): Maya Thurman-Hawke has been cast in the series regular role of Robin, "an alternative girl who is equal parts sharp and playful. Bored with her mundane day job, she just wants a little excitement in her life… and gets more than she bargained for when she uncovers a dark secret in Hawkins." Priah Ferguson has been promoted from guest to recurring. Her character, Lucas's blunt and opinionated little sister Erica, "returns, only this time with an army of friends. No longer content with sitting on the sidelines, Erica finds herself on a wild mission to save Hawkins from a dangerous and unexpected new threat." The Duffer Brothers will again serve as showrunners for Stranger Things 3. Shawn Levy continues to produce and direct. The third series will have eight episodes, down one from the second series but right in line with the first series. The extra episode in Stranger Things 2 was used to tell a standalone story with Eleven outside of Hawkins. The episode itself, and its placement within the season, proved highly divisive with fans. Production is set to begin next month in Georgia.
