The sequel will arrive on September 21st, 2018.

Rob Letterman is on board to direct the follow-up to 2015’s hit family horror film, which is tentatively titled Goosebumps: Horrorland. We have been assuming that Jack Black would be reprising the role of R.L. Stine in the 2018 movie, but it wasn’t until today that we actually got some concrete confirmation on that.

Over on Twitter, Stine himself revealed that both Black and Slappy will be back!

Yes, there is a script for the Goosebumps movie sequel, and I am told that my evil twin, Jack Black, has signed on. More news to come! — R.L. Stine (@RL_Stine) June 12, 2017

The Goosebumps movie sequel is tentatively called Goosebumps Horrorland and is slated for September, 2018. Watch out for Slappy! — R.L. Stine (@RL_Stine) June 12, 2017

The Horrorland books are set in a vast theme park which R.L. Stine describes as “the scariest place on Earth.”

Darren Lemke wrote the script. Deborah Forte and Neal H. Moritz return as producers.
