Wendi McLendon-Covey, Ken Jeong, and Chris Parnell are joining the ensemble of “Goosebumps 2,” sources tell Variety.

They join the previously announced cast of Madison Iseman, Ben O’Brien, Caleel Harris and Jeremy Ray Taylor, who are set to star.

Ari Sandel is developing the project, which is one of multiple iterations based on the dozens of books in the series that the studio is developing.

Neal H. Moritz of Original Film and Deborah Forte of Silvertongue Films are producing.

R.L. Stine’s book series has sold over 350 million copies worldwide and inspired the studio to make a movie following the books’ author, played by Jack Black, and what happens after his stories begin to become a reality in a small town. 2015’s “Goosebumps” went on to gross $150 million worldwide.

Plot details are currently unknown, but are expected to focus on iconic characters and storylines featured in the “Goosebumps” series. The pic is set to bow on Oct. 12.
