The “Goosebumps” series at Disney+ has added both Zack Morris and Isa Briones to its cast as series regulars, Variety has learned exclusively.

The duo join previously announced cast members Ana Yi Puig, Miles McKenna, and Will Price as well as Justin Long.

Per the official logline, “The series follows a group of five high schoolers who unleash supernatural forces upon their town and must all work together — thanks to and in spite of their friendships, rivalries and pasts with each other — in order to save it, learning much about their own parents’ teenage secrets in the process.” According to Disney Branded Television, the series is influenced by five of the most popular “Goosebumps” books.

Morris will appear in the role of Isaiah, described as “a popular star football player whose financial struggles at home, has him and his family banking on his athleticism to secure him a full ride to college.”

Briones will play Jane, who “typically has her head in a book, causing her classmates to think she is a snob but she is just laser focused on her writing and creating a life that is interesting enough for a memoir.”

Morris is best known for his role in the long-running BBC series “EastEnders,” appearing in over 400 episodes during his time with the show. His other onscreen credits include series like “The Fades,” “One Night,” and “Children in Need.”

Morris is repped by Elevate Entertainment, CAM, and Felker Toczek.

Briones is best known for starring in the first two seasons of “Star Trek: Picard” at Paramount+. She also appeared in onscreen in the second season of “American Crime Story” at FX, “The Assassination of Gianni Versace.” Additionally, she was a member of the First National Touring Company of “Hamilton” and “Next to Normal.”

She is repped by Piper Kaniecki Marks Management and A3 Artists Agency.

Kevin Murphy serves as executive producer and showrunner. Neal H. Moritz and Pavun Shetty of Original Film, Conor Welch of Stoller Global Solutions, Erin O’Malley, and Iole Lucchese and Caitlin Friedman of Scholastic Entertainment are also executive producing.
