No release date or production start date has been mentioned, with the only true knowledge on Revival being that Flanagan is on deck for writing duties, with an option to direct.
Months ago, CinemaBlend’s own Eric Eisenberg spoke with Flanagan about a mystery Stephen King project that was on the horizon, and it looks like Revival is the project that the writer and King had been personally discussing.
This news came from a THR report that not only announced Mike Flanagan and Trevor Macy as being at work on the project, but also confirmed that the Josh Boone variant of the project previously put into motion has officially stalled.
