Along with Ransone, so far only Bill Skarsgard and Jessica Chastain are confirmed to appear in IT: Chapter 2 as Pennywise and Beverly Marsh, respectively, although it was reported last month that Bill Hader and James McAvoy were in talks to join as Richie Tozier and Bill Denbrough, respectively.
The man has a deep background in the horror realm, so joining IT: Chapter 2 will be a good fit for him.
The adolescent actors from IT are also expected to briefly return for the sequel via flashbacks.
Andy Muschietti is once again directing, and Gary Dauberman is working on the script with Jeffrey Jorgensen.
