According to Omega Underground, a new cast will star in the sequel to the 'Goosebump's' movie: 'Goosebumps: Slappy's Revenge'. The film was originally slated for release on September 21, has since been bumped back by Sony to October 12. However, since its still not yet in production as of now, the October release date is looking doubtful. While the rest of the movie's cast is not yet known at this point, actor Jack Black, who depicted series author R.L. Stine in the first film, will reprise the role in the sequel.
