There is also a Purge TV series in the works, which will be an anthology series and which DeMonaco hopes to put on cable.
Officially we can’t say yet if The Purge 4 will be a prequel, but since DeMonaco is tackling the story, it’s likelier to be the case than not.
While today’s announcement didn’t provide any Purge 4 plot details, James DeMonaco talked last year about how he wants the fourth Purge movie to be a prequel.
However, that project hasn’t been officially announced yet, but DeMonaco implied we may see it sooner rather than later.
